I was curious about Hiroaki Ohta's friction folders and ordered one from one of our contributing dealers. I'm a big fan of Mr. Ohta's work and have 4 of his custom slip joints with stag covers.
This is my first friction folder. This one is an FK5, the top one in the image from Hiroaki' s catalog.
A little knife that couldn't be more minimalistic if it tried. The one piece handle is some really nicely finished ironwood. The D2 blade came razor sharp. The maker's name is in small script on a corner of the handle. The knife has a smooth stiff action and came with a nice leather slip.
At the price of about half a Franklin it was worth it to me.
I'll find a pocket for this one and see if it grows on me.
Here's a few pics of mine.
