Let down by 20CV

I need to try some magnacut. Maybe when the Spyderco military 2 is released there will be a magnacut version.

I have three customs in it, a folder, and three productions fixed blades. It really lives up to the hype. A Military in it would be incredible!

I've yet to buy a military because of the tip down only clip.
 
No issues with M390 for me in customs. Ground 0.2mm behind the edge with a 10-12 dps edge.
 
I have a Benchmade knife in C20V steel that was very chippy from the factory. I sent it back for evaluation and re-grind. They said it tested to HRC60, but wouldn't say "burnt edge.

Benchmade's second grind was perfect, and they must have removed the over-cooked edge that was chipping. It is now a fabulous assisted opening compound grind knife. We all know a proper heat treat and finish shouldn't affect a supersteel negatively. It's a great steel, get it fixed!
 
I have a ZT 0562CF in 20cv. The blade chipped close to the tip within a few days but it sharpened right out no problem. Zero issues since as well. My Hogue Ritter in 20cv has had no chipping issues whatsoever.

20cv is my current preferred steel because of these two knives in particular and is what I look for. That being said my next purchase is likely going to be the Ritter in Magnacut if it ever comes back in stock.

I purchased a new knife in 20CV earlier this year, and let's just say it was from a very reputable US manufacturer. I immediately chipped the blade in a couple locations. One was my fault hitting a staple behind some tape. With that said both times the pressure was very light and in line with the blade. I stropped it a few times thinking it was a feathered burr but the chips remained. I picked up a Work Sharp precision adjust, and worked out the chips to a 17 degree angle. The original grind was between 16 and 17 so I figured the steeper of the two would be better. The edge came out great and I finished with the strop. Fast forward to today after cutting plastic pallet banding, and this thing looks like an old hockey player. It has multiple chips and rolls after cutting maybe ten bands. Is this the trade off for edge retention? This has been by far the most delicate steel on the verge of egg shells I have ever used. I am going to profile it again to 20 degrees to see if there is a change. What am I missing?

Did you match the original edge angle or check to see if you were actually increasing the bevel angle when sharpening? The angle measurements on the sharpener may not be accurate depending on blade width.

I’d go up in angle a couple of degrees at a time until it quit chipping. You’ll eventually get a high enough angle or sharpen through the damaged material, which I think is likely an issue. If the final angle is above a measured 20 dps I’d start dropping back down a little.

I generally wasn’t impressed by 20CV in the one Hinderer I tried. I didn’t have this trouble, but still. I’ve chopped tie wire with large blades in 1055 steel at lower angles and didn’t have any edge damage. I wouldn’t be very happy with a folder that chipped on a staple and cost 10x more than my 12” chopper.
 
In the world of Japanese tools it is often the case that the steel gets better after a number of sharpenings. This is apparently becuase of the difficulty of controlling the heat treatment on the narrow edge of the blade.
