Custom M390 Folder Mirror Finish

Fri Apr 26, 2013 5:46 am

Took me exactly 4 hours 55 minutes to complete with the Edge Pro Professional - NO mechanical devices used - all done manually by hand.

Angle measured before: 26 degrees per side.

Angle after: 20 degree relief per side with 22 degree micro bevel per side.

Relief progression:

Atoma Diamond Plates: 140#/400#/600#/1 200#

Relief Mirror: Shapton Glass Stones: 500#/1k/2k/4k/8k + 1µ diamond spray/16k + 0.5µ diamond spray/30k + 0.25 diamond spray/leather strop + 0.1µ diamond spray.

Cutting Edge (Micro bevel): 15k Shapton Pro Stone - 4 x light strokes per side.

With a precision instrument like the EP, irregularities quickly show on the grindline as either dips or mounds - I am happy to report that this blade presented none, which is extremely rare for a custom maker - well done there.

The heat treat felt very consistent with a slight "hard spot" at the heel, which bodes good, as this is where normally first contact is made when attempting the cut, resulting in a slighter longer lasting edge.

Slight "differential" HT in maker's favor.

I am happy with the final result, but for now, my fingers hurt!

Rook, between your sharpening and cooking skills, I feel like a lost child in the woods.

I'm with Pete. That's some pretty awesome work.

This was still my favorite mirror polish of yours, and even though I am a DEVOUT Spyderco-ite, it's actually because it looks like you opened up the bevel a few more degrees...
