I haven't made a kiridashi in a while.

A little bit of O1 steel, cut off one end at an angle. Tapered one side so that it's not parallel.

A quick drill (using old transformer blocks as drill blocks)


Then round the end - used the drill bit so that the curve matched the position of the hole, pivoting it round.



and then a bit of thinning and rounding in the middle.



It still needs the bevel putting on, heat treating and possibly a bit more rounding of the handle but a satisfying bit of work.
