Hi, first post here.
So I got my Tops Pasayten about a year ago, some design flaws but I liked it in general as a camp/kitchen/game knife. So in past weekend, I tried to strip off the coating on diamond stone because I don't like it.
Anyhow, I got these ''waves'' like in the pic
B004H64MZC
. Are these warping or bad grinding? Should I call warranty for bad workmanship (or at least try)?



If link to IMG fail pls find the image in

TIA!
 
all I see is a link to Amazon Canada for a discontinued knife that is a new pic of a knife? are you trying to show pics of your coating removal with diamond stones as ya said?

I dont know what ya mean by waves in the coating or steel? I dont see waves in the steel or coating on the Amazon Canada picture? I see texture on the coating? is that what's you're talking about?

not following?

were the marks there when you initially stripped off the coating?
I'm betting they are machining marks left over from the CNC machining. Lots of manufactures PAINT their blades, cause it's cheaper than spending time on grinding/finishing the blade.... They say it's for "rust prevention".

-also.... look up Citra strip.... It's a nontoxic citrus paint stripper. It works and smells Nice.
Won't screw up a diamond stone..... :/

Ye, so in the (one star) review. You see the un even grind mark.

ahhhh....he thinks its bad heat treat. least said so in his review. it isnt bad heat treat its just level of finishing for a coated blade, like ya said.

One of my favorite blades.... 1311 looked WAY worse than his. I Wish mine looked like his. I'm still grinding/smoothing it out occasionally.... whenever I get a bug Up my rear.

To the OP.... Think of knife modding as part of the Fun.... and a learning experience.
you will learn new skills, maybe making knives of Your own someday. ;)

Glad to be here. So these are there when I started and I felt it before the strip which I thought it is a change of angle.
It is possible during CNC when the mill the ffg the blade had some play and the bit bite in a bit more.... so do I just live with it or get a good stance to the warranty? I mean for the price, this is just dun dun.

It is a mod knife now... but I gotta hand Tops this, the paint is great and I tried several paint stripper, not a din.

Assemble my Brisa nessmuk today. And for a knife for half the price, Brisa know how to keep a flat bevel.
 
I think that is just machining marks. I wouldn't worry about it. I don't think you'd have much chance of warranty after taking the coating off.

I'd have to look again, it was prob just some tiny vibrations during the cycle. Maybe their jig isn't supporting the part as best it could....but since they Know that the coating will cover all those marks....it's No Big Deal.

Only you can decide.
* me personally, I really like that overall knife design, and it has been on my radar to someday own. Looks like a Very useful blade.

I'd buy a diamond file, from the Big River, and gently "Buff" the marks out.....
 
Stripping the blade can void the warranty, especially if you used abrasives instead of a chemical stripper. Coated production blades, like TOPS, Beckers, or KaBars, can have quite a bit of pattern under the coating. They are taken down smooth, but some grind lines are left in if they are going to get covered up anyway.

This is just a guess, but you took the coating off with a diamond stone and I don’t see any coating left. That means that you were running diamond over over the bare steel in some spots, because the coating doesn’t give way cleanly. Some of those marks are going to be yours, which makes a warranty claim unlikely to work. Those marks will come out, sanding it on a flat surface will take it out though. There are some great threads on sanding out scratches in the Maintenance sub forum, and automotive stores sell these convenient sandpaper packets that go from low number grit to high number grit wet sand.
 
I wouldn't be bothered by a few minor flaws in the surface of a user/camp knife.

Naturally we want our knives to come perfect from the factory, but we live in the real world. And if that knife did have a perfect surface underneath the coating it likely would have been more expensive.

I assume that any blade with a thick coating is going to have a bit of a "rough" surface underneath the coating.

^ perfectly said there.
 
Here’s the kicker...sometime you need to leave coarse grind lines so that the coating will have something to “bite” onto. If the blade was perfectly smooth, the coating could quite possibly chip off during use, or if dropped. And that is a no no.
 
When you perform a mod like you did, I doubt any company would back their warranty. Like said before a coating is put on some blades so they don't have to spend the time on the finish.

I'd say this Isn't true..... I'm not sure about Tops? But their peers like EESE, Busse, and Becker wouldn't care about their coatings being removed.....

It comes off during Chopping. Which IS normal.
The OP was Just doing it quickly and evenly......

Not a void in the warranty.
 
Interesting points in the review. I was unaware that TOPS claimed a differential heat treatment or a 90 degree spine for the Pasayten. I haven't stripped mine and done Rockwell C testing near the spine and near the edge to know either way. I do know that the Micarta handle on mine isn't slippery at all and it gets grippier when it's damp.
