For quite a few years this Buck Strider 881 mini tanto in BG42 steel was gathering dust in a drawer, as to me it was more a knife-like object, literally unable to cut anything.
Over the last few weeks i changed that with the help of my Tormek SB-250 stone (for the point area), a 300 grit diamond file, a Foss 7205 black/green silicon carbide stone, and some 400 grit wet & dry SiC paper on glass (for the straight edge)
The apex on the now full convex blade measures somewhere between 22.5 and 25 degrees inclusive, and i'm first going to do some test cutting to find out if i can safely lower it a bit more.
Also rounded the overly sharp G10 grip plates a bit and sanded the screw heads.

After the 400 grit SiC paper and removing the tiny burr on a piece of hard cardboard with a dab of 1.0 micron diamond paste:
Considering all work was done with only one eye currently functioning at about 80 % (plus a pair of reading glasses) i'm quite pleased with the result,
