A froe (or frow), shake axe or paling knife is a tool for cleaving wood by splitting it along the grain. It is an L-shaped tool, used by hammering one edge of its blade into the end of a piece of wood in the direction of the grain, then twisting the blade in the wood by rotating the haft (handle). A froe uses the haft as a lever to multiply the force upon the blade, allowing wood to be torn apart with remarkably little force applied to the haft. By twisting one way or the other the direction of the split may be guided.[1]
why the f*ck are you sharpening a katana like a vegetable peeler, it's a combat sword with steep slopes and the sharpening degree should be no less than 40 degrees..I won't even talk about "hardening". Man, don't be offended, but you'd better continue restoring kitchen knives, you're not capable of more...
Sry, aber furchtbar. Hättest es mal rostig gelassen. Alleine das du Yakiire bei Tageslicht machst, disqualifiziert dich. So leid es mir um deine ganze Arbeit geht, aber du hast das Schwert nicht Restauriert, du hast es Zerstört!
