    Thank you zimKnives. I grind down the back on drop points and Santoku knives, but find the upswept shape more natural for most other knives, but as I said in my other video, there is no one right way. I appreciate the feedback... Yes, I take a huge amount of pleasure in the sharpening process.

    This is the best video on fixing a knife on all of youtube in my opinion. I have a Spyderco C149GP Vallotton Sub-Hilt Folding Knife I've been scared to touch myself. I think I'm going to just go for it now. This video really makes me confident I can do it myself.

    I'm new to sharpening, so i'm a little confused.
    Isn't a Trizact A30 like a 600 grit, but you follow that with a P400. Is there a difference between the Trizact grit and regular 400 grit. I thought it was a universal thing?
    Also - you strop on a leather belt with chromium oxide compound. Chromium Oxide is supposed to be 0,3 micron, so going to white rouge on a leather wheel is again confusing.
    But maybe all green compound isn't pure chromium oxide.
    Thank you for an otherwise great walk through of you process

    • @PatronSaintofKnives
      @PatronSaintofKnives  2 ปีที่แล้ว

      I can’t even remember that far back. Currently I use almost exclusively A100 Trizact. Since it doesn’t load up, when it wears down, I move it to the next machine and use it as a finer grit.
      I then use the green compound on either a felt belt (lasts longer than leather and is cheaper) or a hard felt wheel. Then I go to a hard paper with blue compound.
      Since I did that video, sharpening has taken over my life and I do about 17,000 knives a year. I’m also doing a lot of TikTok stuff @patronsaintofknives if you dig through the videos there is some information there.

    • @petergdk

      Thank you for the update :)
      I hope you are doing well for yourself.
      I'm not sure what the different compounds are, and which are finer. I always thought the chromium oxide was the finest grit, and after that honing was done on the smooth side of pure leather. But i guess blue is even finer. Always thought that was for aluminium :)
      Hope you will do an update video, and show your present sharpening system :)

      ​@@PatronSaintofKnives Thank you for the insight into compounds - i will see if i can source it here in the Swedish sticks.
      You are very inspirational. Have looked through your website, and your business model is inspired.
      Have just built my own 1x60 belt grinder with VFD, and further bought and renovated three 1x30 belt grinders with one of them having gotten a variable speed DC motor.
      Also 3 bench grinders with felt, leather and paper wheels, and a 20 inch motorized sandtone grinder plus a Tormek knock off. I think all in it has cost me $600
      Sounds like i have invested a lot of money, but apart from the VFD, everything was either free or dirt cheap.
      So even though i'm a newb the finer points of knife sharpening, i have started sharpening for people.
      Since i'm new to it, i spend way too much time on each item (like 30-40 minutes), because i don't want to send a knife out of the door that isn't so sharp, that it can split a piece of free standing newspaper.
      So i have also splurged on diamond spray i 2, 1, 0,5 and 0,25 micron, and have made my own chromium oxide honing paste. But would much rather use cheaper compounds.
      But people are happy, and i have sharpened 100 knives for customers at $3 a knife, so consumables are more than covered.
      With time, i will hopefully speed up the process, and become as proficient as you :)
      Also - getting in contact with a wide array of people have yielded other odd jobs, that i actually master, like sharpening chainsaw chains and axes, making handles for garden tools, fixing small engines and doing tree work:)
      I have learned a lot just watching your process, and i appreciate your kind replies and good videos. Hope to see more of them.

    Hi, I just found an old knife metal detecting. It's got a body shape similar to a hawkbill but I don't think it is. It's an odd knife. The handles seem to be brass and the bolster and the handle seem to be 1 piece. It's got 3 small grooves right where the bolster would normally meet the handle. I just started to clean it. I've had it soaking in vinegar and salt since this morning. Should I try to take it apart? It's really got a lot of hard rust on it. Should I just see what the soak does and then try penetrating oil to loosen up the blade? This type of restoration is new to me. Vices and heavy steel is 1 thing. But this could be civil war Era no? Massachusetts by the way. Thanks.

    Great video! I am interested in buying the Work Sharp knife and tool sharpener mostly to learn to restore damaged tips. I have heard that the belts, even a low grit, can ruin the temper on a blade? Do you find this to be true? And can the temper be restored then by hand sharpening after one restores the tip with a belt?

    • @PatronSaintofKnives
      @PatronSaintofKnives  9 ปีที่แล้ว +2

      +David Shaffer Hi David,
      I understand the concern. One does move as carefully as possible in order not to heat up the blade. People debate this issue nearly to death. What I can say is this, I sharpen thousands of knives a year with an extremely loyal customer base who find that my work is sharper and stays sharper longer than anyone else they go to. At some point one needs to stop debating and accept the customers feedback. Everyone works differently, but when your business survival is completely dependent on your ability to keep customers happy then at some point you have to accept that what you're doing is working. The Worksharp is an excellent tool, as is the Wicked Edge and a number of other great products. The bottom line is, is the customer satisfied? Particularly when you're dealing with avid hunters, fisherman, chef's, and dedicated home cooks... When you screw up, you hear about it.

      +Fariko Mike Hey Mike, It totally depends on the original shape of the knife. I would usually scrape off the back on a Santoku and then off the front of a chef's knife. Sometimes a little off both sides to make a natural shape. It's all about what looks natural.

    • @PatronSaintofKnives
      @PatronSaintofKnives  6 ปีที่แล้ว

      Alan Moore The cheapest thing you can start out with it’s a small harbor freight belt sander. They are inexpensive and the last basically forever. Nowadays, I use Viel belt sanders almost exclusively. They run a little slower and the longer belt lasts a bit longer. Both of these Sanders can be run either horizontally or vertically which is crucial to my technique. There is absolutely nothing wrong with the harbor freight sander, just be very careful about pressure. Too much pressure or moving too slowly will burn your edge. Buy a bunch of cheap knives the Goodwill and practice a little bit.

    Thank you for your very informative videos. They are full of knowledge, experience and valuable insight. I have a question though: How would you go about repairing a broken tip on a scandinavian grind knife? If it's not severely broken, but only a few millimeters... Also, do you also use this method (belt sanders) of sharpening on scandinavian and flat grind knives? I guess it wouldn't work on those due to the requirement of a flat hard surface, but still I would like to hear your thoughts on that. Thank you very much for your reply in advance. Regards from Portugal :)

    • @PatronSaintofKnives
      @PatronSaintofKnives  10 ปีที่แล้ว

      Hello Emanuel,
      Thank you for the note and the question. While I personally prefer a long convex shape to my blade, the flat skandi edge can be attained by the careful use of the hard platen behind the belt. As I mentioned in the video this is less forgiving of any subtle mistakes you might make in angle. You might consider starting on the flat of the platen and finishing up on wet and dry sandpaper glued to a piece of glass for the final polish. Also, when working absolutely flat, a jig of some sort can be very useful. I hope that helps.

      @emanuelantunes2789 10 ปีที่แล้ว

      Patron Saint of Knives Thank you very much for your prompt reply. It was very helpful and gave me some good ideas.
      I just have one more question: Could it be easier to grind down the spine of the blade near the tip to a flat surface slightly changing the spine angle at the tip? The knife I have to repair is a Mora Companion, it has two flat surfaces on the spine, I was thinking the best way to repair it without changing the angle of the scandi grind would be to grind the second surface of the spine near the tip, flat until it meets the new tip... Are there any drawbacks to this method in comparison to the one you use where you basically create a new cutting edge? Thank you very much.

    • @PatronSaintofKnives
      @PatronSaintofKnives  10 ปีที่แล้ว +1

      Emanuel Antunes Hello Again Emanuel,
      There are many people that prefer to take metal off the back of the blade instead of the front. There are no written rules here, just like there is no one perfect way to sharpen a knife. Technique and practice are more important than what particular method you use. Personally I find it more esthetically pleasing to reshape the cutting edge of the blade, but it is true that taking metal off the back is easier and certainly workable. For esthetic purposes, you might want to take it all the way back to the crest midway back on the spine, but that's just for looks.

    I haven't seen anyone remove this much metal from a belt before, seems like it would wear out a belt fast,
    is there some reason why you wouldn't use a grinder?
    Also, I thought only the edge of the knife is tempered;
    This is cutlery, I see you put a convex edge on this knife,
    is that usual for cutlery? I thought cutlery used a standard v edge
    Thanx, love your attitude and the great work you do

      @PatronSaintofKnives  8 ปีที่แล้ว

      sun Tao Hey Sun,
      I find it easier to control both the shape and the heat on a belt. Since that video I have started using a much rougher belt for the reshaping as well as a table for easy angle control. The rougher the belt the less heat is built up.
      The whole blade is tempered the same in western knives. It would be hard to sharpen effectively otherwise. The blade would get softer the more you sharpened it.
      There will be updated videos when the new shop is done!

    • @PatronSaintofKnives

      It occurred to me that I should mention… I would never use an actual bench grinder on the edge of a knife that I was sharpening unless it was a water stone like the Tormek. It's very hard to control the contact point and heat is almost instantaneous.

      When sharpening multiple knives, you generate a lot of metal dust, which gets into everything and is hard to clean off. Also, I often get white handled knives and don't want to get the handles dirty, so I switch gloves as needed. When I go back into the house I take my gloves off to keep my wife happy too.
