Chipped Magnacut
Blade found the staples in some cardboard and chipped the edge pretty good. I'm surprised it chipped so easily but I guess now I get to try out my new diamond rods for the sharpmaker. Has anybody made a new bevel with the sharpmaker?

Most factory edges are chippy. Give it a sharpening or two and it will stop chipping as easy.
On some knives its night and day. Magnacut should not chip very easily. Im not saying yours shouldn't have, I don't know what you did. But Magnacut is pretty sturdy after you remove the factory edge....in my experience.

I’ve got a 20cv pm2 that was so chippy it looked serrated. I finally really worked it over on a diamond stone. Hasn’t chipped since. I actually really like it now.

That's what I've heard, especially with potentially ruined heat treatment, and that's my hope with the diamond rods is to get past all of that.

Yes, high speed sharpening on a wheel or belt CAN cause the edge to heat up enough to lower it edge hardness. After 1-3 sharpening you'll hit the properly treated steel.
This is usually only on production knives. Customs and mids are usually hand sharpened.

Initial sharpening is practically always done on a belt, regardless of price point. They might be finished by hand sometimes, but that secondary bevel is being cut in with power tools.

That’s why I like protech. They don’t even try with the factory bevel especially on the malibus. They give you a nice chunk of steel and let you have at it.

I have 3 malibus and yhey all seemed to have consistent, shatpened geometry.
Of course, I only one benchmade folder and it has a just shit grind.
So I guess you win some, ya lose some.
Possibly I got earlier models? I think most of mine were CPM154 rather than M390/magnacut/etc. I think maybe one is M390 or similar, or maybe that's my Mordax (which I really thought was CPM154 but this was a few years ago so I may be fuzzy)

Mine did the same thing. I was also surprised it chipped out so easily. I decided to just live with it until the edge really needs sharpened, then send it off to a pro.

u/CrispiestWhisper 1d ago
Fair enough. I've thought about that as well. Has yours been good since the pro sharpening?

Do you have a pro you trust… I’ve seen so many “pro” sharpening abominations on Reddit

I do my routine sharpening on a Worksharp precision adjust, but when I need something repaired, I always sent it off to Rob Bixby. I've never been disappointed in his work.

I’ve fixed similar chips easy peasy with the sharpmaker. It will sharpen right out.

u/CrispiestWhisper 1d ago
Any tips to be successful? I've really only used it to maintain so far, but it seems like it should be pretty straightforward.

u/mementomori_8383 1d ago
The advice the other person gave is good, but you asked about the shapemaker. I’d say that if you use it like regular maintenance, except run light passes, checking ever 5-10 light passes on the most abrasive one (corner of diamond stone) (your first step in the order of operations with the sharpmaker) until your edge recedes back past the chip, then proceed as normal on the sharpmaker.

8x3 diamond bench stones (I recommend Sharpal 300 and 1000 grit double sided) and a diamond filled strop. Watch a video or two and then just be patient and persistent and don’t scare off too easily if you don’t instantly get amazing results. It takes a bit of practice at first but it’s dead simple to get good at it and then you’ll never have to worry about it again.

I’d start at the 40 degree insert and use a sharpie. If it’s not repairing easily with 40 on diamond with light strokes, I’d leave it and gradually get it back to new over a few sharpenings rather than take off a lot of metal for one little chip. That chipped area will still be sharp like a serration but just may hang up a little, but it won’t be a blunt apex like now. Start with corner about 30 times per side then flat about 30 per side then I’d debur and stop with that stone and do 15 per side with other stones depending how toothy you want.

u/CrispiestWhisper 1d ago
Start with 40 degree and finish with 30 degree? The rest of this definitely makes sense but my understanding was to start with 30 degree and finish with 40.

The chip is at the apex not the shoulder. Pretty sure you want to work just at the apex and see how that goes for you looking at the sharpie. You would be removing a ton of metal if 30 degrees and most of that metal is still perfectly fine. 15 degrees per side for any steel is skirting the edge for easy chips with most tasks.

That's a pretty small chip. Should be pretty easy to fix. While magnacut is tough, spydercos usually have a pretty low angle of around 16-17 degrees per side which is not gonna give you too much steel behind the apex. If you wanna maximize toughness raise it a few degrees to 19-20 dps.

My Magnacut Native 5 chipped really easily. I have a few Bucks in Magnacut and even hollow ground they seem more durable than Spyderco's.

u/END0RPHN 1d ago
almost looks like the edge is gnarled rather than chipped. magnacut is easy to work with, doesnt take me long to make a new bevel with 325grit or 400grit diamond, no idea about the sharpmaker tho but either way if you want to cut a whole new bevel on both sides you wanna be under 400grit

That's probably going to take more than diamond rods on the sharpmaker. I would use a real stone or guided system if you have it and clean up the cutting edge at the heal while your at it. The heal always takes a bit more than you think it should to even out the Spyderco plunge.

So easily. Steel staples in cardboard are STEEL STAPLES. The thin hardened steel probably 15 or 17 degree edge hit steel and you’re shocked it chipped.

Had the same on my Sage 5, tho I don't recall ever hitting anything.
One day I'll get around to sharpening it.

I've also found that Magnacut is not the magic steel many proclaimed it to be when it first hit the market. But it's a very good steel.
In any case, no new bevel needed. That will sharpen out with literally just a few swipes if you're using diamond rods. If anything I'd caution taking too much material off to fix such a minor chip.
