Hello Knife People,
Do you have a sleepy knife?
I’ll bet you do, or at least you HAD one but you woke it up…
How do you wake up a sleepy knife? Geometry of course.
Here’s a selection of my knives that were a little sleepy but have been woken up with some thinner geometry:
I re-profiled the edges of most of these myself, however the CS Talwar - second from the top, was sharpened by Sergey V. Pikiner, and the Scrapyard AD6 - fourth from the top, was thinned and given a convex edge by
David Mary
.
Many knives sold today seem to come with fairly obtuse edges, often more than 25 degrees per side (dps). Edges at these angles are difficult to resharpen freehand (which is absolutely the best method for 99% of sharpening tasks) and they don’t cut very well even when sharp.
I have found that if I reprofile an edge freehand, trying to hold about a 16 dps angle, I end up with a nice shallow convex edge with an apex of probably 18-20 dps (due to freehand “wobble error”). This seems to be the sweet spot for most knives - from kitchen knives to choppers - although I go even more acute for certain knives.
Recently I came across a video from OUTDOORS55 on YouTube, (highly recommend channel for sharpening information), who suggested the Shapton Korumaku orange medium ceramic wet stone (~1000 grit), and I wanted to pass along this recommendation.
It’s a wonderful, do-it-all stone that has an unusual combination of very fast material removal, high hardness/durability, and the ability to create a shaving edge. If I could only have one synthetic stone, it would be this one.
I recently used it along with my 16 degree Lego angle guide, a Spyderco ultra-fine bench stone, a homemade sharpening rock and a homemade diamond impregnated strop to create a scary edge on my Busse DDSH.
Have you ever woken up a blade?
Let’s see it.

In its current state it is a maniac kitchen slicer in spite of still retaining it's full factory spine thickness. When I'm not roadtripping & in my home kitchen it's placed at the end of the magnet bar so it's easy to grab & is my default go-to blade. 
, however. Always perks me up, once I get them cutting the way I want them too. Almost universally, that means thinning out the edge grind at least, and sometimes the grind above it as well. Some of my favorite examples are below.
