Patina on Tojiro ITK Shirogami

Wed May 08, 2013 8:48 pm

Mark
ordered a 150mm Tojiro petty.
2 questions.
can I force a mustard patina on the unfinished surface?
how hard is it to remove the black finish and then patina the whole thing?

Yes you can force a patina on the polished edge.

I've seen a bunch of guys sand the whole blade and polish it up. It takes some work to do but it's certainly possible.

It'll take you a few hours of work by hand to remove the KU finish. Use a relatively soft sanding block and avoid any block that's too hard. The harder the block, the flatter the surface will have to be make the finish uniform. A softer block gets into undulations in the blade a lot easier.

i removed the KU finish from my 240 ITK using some 80 grit paper then progressed up to 2500 to a mirror polish.. didnt really matter bc of the patina it took afterwards but it looked great for about 30 minutes haha. all in all it prolly took about 3 hours of elbow grease. looks like a much more expensive knife now tho :)

JEFF <> I STRONGLY suggest forcing that patina as those knives are notoriously reactive.
