Recently reprofiled ALL of my spydercos (ow my hands). Here's what I've found interesting from the experience.
This was my first foray into PROPER sharpening. Fully decked out kme. The goal was to even out the base of the edges on all my knives. sharpening out a slight recurve on my watu, removing unsharpened bits on my waterway, native, and laydybug. and just generally fixing up my spydiechef. All were full reprofiles. So, K390, 20CV, LC200N. I was pleasantly surprised. They're all about on par with each other in terms of sharpenability. I had maybe a little more trouble getting a burr with 20cv, at least on the higher grit plates. And I found some interesting bits about the grinds on all my knives. All were at a no frills 20dps, it's what my kitchen knives are roughly at, those work great so 20 it is. As such I can clearly see which of my knives is the thinnest behind the edge.
The native is far and away the thickest, although it gets brownie points for having a 100% even grind.
The spydiechef is just BARELY thicker behind the edge than the rest. And came with a really tall uneven bevel. I still haven't totally fixed that. It's also (at my estemation) run a bit harder than the native, since it was a little bit less receptive to the lower grits.
The waterway is a slicey boy. This thing is a testament to how wonderful lc200n is. I have beat the snot out of this, more than any other of my knives, with minimal upkeep. Not a chip in sight. And even with how thin the edge is it can plow through whatever I throw it at. Wasn't to bad to sharpen out the nub on this one, although it's likely a little thicker at the belly then it is at the tip or base.
And tied for thinnest it's the Watu and the Ladybug. Yes the Watu is as thin behind the edge as the ladybug. Yes you should buy one. The ladybug wasn't too bad, k390 isn't as scary as I thought it was. Although it kicked up more metal than any of the others... And one concerning bit on the watu is that there appears to be a thinner spot about a milimeter from the base of the edge. I'm really hoping this is either not going through the full height of the blade or is caused by user error because that would be a not so fun structural problem.
All in all. Lc200n is still wonderful, K390 isn't too scary and is great at cutting through cinder blocks, 20cv is a wonderful all arounder, and they're all just about as easy to sharpen. The occasional 10 minute touch up session will keep these guys trucking for ages.
Patiently waiting for… MagnaCut?
