And I just got the thing! I'm a truck driver and I had to cut a piece of mudflap that was hanging off the side of a trailer. I'm guessing there was some sort of wire reinforcement inside the rubber. Anyway, it's chipped up pretty good. I've never progressed from my sharpmaker as far as sharpening. I have the diamond rods but I don't think that's going to cut it and I'm not feeling inclined to dish out the $$ for a better system.

Anyone know of a sharpening service that I could send this thing to?
 
There have been a few threads about this subject ... I really like my Spyderco knives but their Maxamet has been known to chip or break doing much less than you did. I don't know the extent of the damage and I am not sure what work Josh at Razor's Edge is taking right now, but i would contact him and ask. @razor-edge-knives is his nic here.

How bad are the chips? I chipped and broke a tip off a S110v Manix 2 recently. I used an inexpensive DMT diafold with blue coarse and made quick work cleaning it up. Didn’t take too long.

That said, be careful with these high carbide steels. They destroy cardboard but don’t seem to like any kind of lateral pressures.

I think you should try the sharpmaker with diamond rods in 40 degree slots before you send it out, what’s it going to hurt?

I’ve chipped mine up badly and the sharpmaker did an excellent job, just took a while.
 
Another vote for sending it to Spyderco. You'll only pay shipping, and they will do a good job.
 
I don’t understand sending the knife out when you have a foolproof way of sharpening it.
I’ve sharpened hundreds of badly chipped knives, and it’s really not a big deal.
 
I have a knife designed for truck drivers. It is a custom and has O1 steel at about 61Rc in a warncliffe shape. The maker said the client wanted a knife that could cut off pieces of flaps, hoses, etc. It’s a big slipjoint with extra wide liners and steel pins.
 
There is no such thing as "foolproof" when there is a human being as part of the equation. Maxamet can be intimidating to a novice as sharpening.

Yes but with minimal effort I'm sure we can walk him through the proper use of a diamond rod sharpmaker to repair his knife. Makes no difference the blade steel with the right abrasives, maybe taking a little longer, maybe not.

Were those knives extreme examples of steels whose properties more closely resemble carbides?
 
I came very close to buying A Spidy in Maxamet last week, I`m not concerned with sharpeneing, been doing my own for 40 years but the steel being brittle was my concern, as I do use my knives for more than cutting paper/cardboard, the more I read about Maxamet, kind of glad I did not pull the trigger.
 
I was never interested in Maxamet other than the cool name. It has weaknesses I just did not want to put up with. However, I know a lot of people love the stuff. I like K390, on the other hand, and have had no chipping, at all.

No, mostly not. But since the mid eighty's, I've heavily used knives made from m35, m42, and t42 parting tools. More recently it's been m2, m4, maxamet, rex45, etc. Always repaired and sharpened myself.
Most all the knives I repair/sharpen for others range in unknown Pakistani to d2/154cm/vg10 class.

Grinding out chips and rolls is just a matter of time. Where I find the big difference is finishing. Different abrasives, and sometime techniques may be required, depending on the steel and how it was heat treated.

Maxamet can take longer to grind, but very easy to de-burr and get a finished, clean and healthy edge, often taking less time and technique overall.

I've had a few Maxamet blade, and even sharpened them...

and K390 is everything I ever dreamed Maxamet should be.
