Axe Edge Geometry & Performance Considerations

- The question of what the perfect edge angle seems to be a never ending debate. This video by no means covers it all but hopefully gets the point across that there is more to it that just the sharpening angle.
Everything from steel hardness, edge shape, bevel angle, weight, leverage and bit thickness effect how an axe will cut. Even things like soft or hard wood and ambient temperature will change how an axe works. Not only that but there are specialty grinds and circumstances that require sharpening an a certain way.
In conclusion there is no one grind fits all solution. This is something you need to be able to modify on the fly to something that will work for your situation.

Thank you so much for patiently explaining with clear illustration on how to sharpen an axe, blessings.
This is the most informative video I have found on the subject. I am just broadening my skills an have a beautiful bearded ax on a standard hawk handle from H.B. Forge an have had a hell if a time getting it dialed in. Thank you.
Need more videos like this. Love the technical side of classic tools. Thanks for all your work.
Chris G glad you found the video informative.
That's one thing that seems to be lacking. Both technical info and history. Which are both good to know. I try to keep them brief so they get too monotonous.
Well said thank for keeping up tradition.
Good stuff! Wish I had this video years ago when I was first learning about edge geometry.
I’m a recent subscriber to your excellent channel. You obviously know your stuff and present it well in high quality videos. Thank you.
Just got into taking care of axes! Great video and everything is explained great!
Thank you for the great illustration!
all the information i needed. thank you!
Well done. Thank-you for taking the time to make these vids.
Thanks for watching. I've never been good at taking compliments but I'm glad you're enjoying the channel so far.
Great information. Thank you.
Thank you sir. Now I know what to do.
Damn good video man! Great info. Thanks.
Great video.
Thanks for your value-adding content, sir! I found you on East Coast Lumberjack FB page. Glad I did.
Glad you like the channel and found some good handles. That's win win. I've used his handles on a few projects now and I'm pretty impressed.
Ty for this. I have been getting some axes ready for work. I like using hardwood and the angle is bad from factory.
good detail thanks
Good description of edge geometry.
Subbed!
nice job on the vid
Thank you. Good video.
Thanks Petre.
Great video. Can you do a similar video about splitting axes and splitting mauls?
Thanks Curtis. I sure can. I'll add it to the list. They're much simpler but there does seem to be some confusion still.
This video is absolutely fantastic. I have so many questions.
Thanks BS. You have so many more questions or you had those questions answered?
I'm going to work on some axes and then see what comes up!
Was wondering if a thicker chisel edge would be sturdy enough to withstand chopping smaller tree limbs and bits of wood
If anyone who has done much chopping would want a rounded edge instead of a straighter edge, I would be very surprised. The perfect shape for chopping is the geometry of an unused, from the factory Kelly Perfect axe! A rounded edge is the result of dulled corners being ground down to an edge because of missed licks causing more damage it those areas.
yeah i learned something .
Don't forget the rounded edges on a hunting ax are for skinning so you don't want a square head on your ax because the blade would cut into the hide more also it would have a round pummel for beating the hide.
Do put a micro bevel on an axe with the file or honing stone?
Yes I do
What would you recommend for throwing axes? Or a tomahawk to be specific.
Jen farmer playtime lol
What is a good vintage cross grain cutting axe ? What is a good vintage splitting axe ?
Hults Bruks Arvika is great for both. Not really designed for splitting, but works well, I split a cord or two this summer with one.
I think I need a slicing, low angle edge axe, essentially a plane to shave wood. Which vintage axe would you suggest please ?
Pretty much anything would work. You'll just need to create your own edge geometry. Otherwise a small side hatchet would work. They're beveled exactly like a plane.
They're good those.
I agree
What geometry would be best for cutting into flesh?
Katana...foolish Gaijin...you looking wron' vidjo!
Whats the best grind for a rigging axe?
It depends on the intended use but I would say a very slightly convex edge would work well for most things.
You should make a video with felling axes that have different head patterns (Jersey, Connecticut, Dayton, Swedish-American) and compare their performances.
Thanks for the sugestion. I probably will in the future. The problem is its so tough to compare. Patterns don't matter so much as weight and length. A thin 7lb head on a 42" handle will always beat any 3lb, 32" axe.
But then practical size also comes into play too. Most large felling axes are more for professional use. Or at least very task oriented. Full size axes are generally over kill in most areas. Where I live in northern Alberta I basicly only have small poplar, aspen and birch to work with. So even a small forest axe or boys axe is more than enough.
I see. Thanks for the input. I do have the small forest axe and was looking into felling axes and there are so many patterns so was curious how they impact the performance. You are right, weight and length do matter more.
Right. It was a good idea though. I think lots of guys have a small forest axe or even a full size forest axe and would like to see how they compare. Maybe a good video would be showing how big of difference there is etween the sizes.
That would make for an excellent video. Please, for the sake of us mortals with just a few axes. try to make it happen.
That video is scheduled for next Saturday. I've been trying to stay ahead on my videos so I can post a new one every Sat morning.
That's demystified and swept away a lot of the BS.
As has been said " why would you spend a lot of time polishing to a shaving sharp edge on a tool you're going to whump into a lump of wood with knots in"....?
Horses for Courses I guess...but you said that too, didn't you....😉.
Your drawings seem to be off....lol idk maybe it's just me but except for the chisel grind there all pretty much the same
There's hundreds and hundreds of years of blacksmiths that would say otherwise, where the geometry of blades, bits, and edges are and were a very major factor as to the quality of the piece and the blacksmiths themselves. There's more info out there on blade/edge geometry for swords rather than axes if you're keen on checking for yourself, but the essence is the same
13 mins to explain this?
