TLDW #5 - Carving an Aikuchi Tanto Koshirae

**WARNING: This is the longer process version intended for serious students of knifemaking. Watch the overview edit here: • SOTW #8 - Creating a H...
Hand carving a classical tanto style mounting from reclaimed and local natural materials using traditional Japanese woodworking tools.
The wood for the scabbard and handle core is Nootka Cypress, the smaller fittings are Oceanspray ironwood.
A note about the wooden koiguchi: I don't recommend this method with any wood other than Oceanspray ironwood due to its peculiar strength in cross section...wood (or better, horn) grain should run vertically across the opening to add strength to the koiguchi in the correct areas.
The abrasive plant material used for fine sanding/polishing is dried tokusa (polishing grass), known as horsetail in english...the plant cells contain silica and it can be used dried as is or glued to wooden blocks with sokui.
Sokui is rice paste glue, the best tasting rice makes the best glue...using yesterday's rice is the optimal time for mixing and mashing completely before adding any water is recommended...read more about sokui here...
