Hi everybody,
I have a 710HS which I used for 10+ years as my main edc knife. It saw regular and sometimes hard use. I kept it sharp with my spyderco sharpmaker and my edgepro system with good results. The mechanics are still in perfect working order: opening and closing is silky smooth with absolutly no bladeplay whatsoever. That was the good part of the story..

But alas, due to the long use and the sharpening I lost a good amout of the blade width, it might be as much as 2 mm. As a consequence the primary angle of the blade is quite obtuse.

Now I am thinking of what to do. Is ist worth to have the blade thinned out, to reduce the primary angle , should I just use the knife for good, or would it be better the get a new blade and dispose of the used one?
I don't think that I could get a replacement blade from BM, as the M2 version was discontinued long ago. So I either could get a D2 version or a custom made one.

What are your recommendations?

Thanks for reading,
Bolle
 
First I would love to see pics of this beauty!!! But you can send back t benchmade for a blade replacement and will most like be d2, I would do a regrind and use it like that and worst case send in it for a blade replacement

Ditto. With the right grind that knife can give you another 10+. I would suggest sending it in for servicing, and maybe have them take the recurve out in favor of something with more belly for better balance. Seriously doubt any M2HS blades are available, more than likely they would replace it with a D2. I would keep what you've got!

M2 replacement blades of any type have not been available for many years now, I checked.
Please don't replace M2 with D2, it'll be a serious downgrade.
Thin the edge and use it every day for the rest of your life, or retire it and pass it on some day.
 
Thanks to all of you for your input, I really that. I will so as you advised me and as my heart told me any way.
I will send it to a renowend knifemaker here in Germany and have the blade thinned out, beadblasted and dlc coated. That should make a good user for use and abuse in the backyard and such.
 
Sounds like a plan and thanks for the great photo~! It would be great to see it after it's cleaned up.
 
Your blade looks very well maintained for a 10+ year specimen. Even the pointy end is still there. The laser etch also holding up very well. A WE system with the proper paddles could do the job.
 
Well maintained it is. :)
I talked to the knifemaker whom I had in mind and he said that it would be difficult to fully remove the bladecoating as it would bond with the bladesteel some how. He also mentioned that a DLC-coating would not prevent the blade from rusting. He advised me to keep the knife as it is.
I will follow his advice. May be I shall get a customblade for the 710 some day .
Without the recurve though.
 
I'm not an expert, but I am not sure that the coating on the blade should be an obstacle. Blades from that period were basically coated with paint, not one of the more modern/high-tech coatings (like DLC). I can see that getting it off before the blade was reground could be desirable, but I am not sure that's really an insurmountable problem. (?) IIRC, people like Klein used to do regrinds on coated Benchmade blades regularly.
 
I would follow his advice. The coating, even though it's worn, will still protect the blade. Better to re-sharpen and use it well!
 
If I remember correctly, those knives used Black T, which was supposed to protect the blade even if it had worn off. Something about it bonding molecularly. Again, going by memory, so I could be completely off.

You may be right. I think there were three different Benchmade coatings before Benchmade got into DLC. At least one was literally Gun-Kote or an equivalent product. Others may be been a little more technical. I know I've seen those blades with Klein regrinds, though, so other people should be able to do it. Thinning out the blade behind the edge could be a major benefit at this point.
 
I had a 710D2 where the BK coating failed, actually came off easily, but was never able to completely remove it. After many hours the results were good, but you could still see the lasered script. On the other hand I used the knife a lot and it never had an issue with rust; so yes it still protected the blade.


 
hello bolle,
sounds like that gem gave you some great service over the years. my suggestion is retire it as is, buy another and look at it often to relive the memories. best regards to all.

Hi Mike,
in fact I do own two brandnew 710HS I bought at the time they were discontinued at ridiculously low prices. So I just could grab one of these from the shelf, but I will try to prolong the life of #1 so that #2 and #3 will serve me to my very last day. :)
I feel kind of attached to this old beater too. And yes : I know it's just a darn knife :D
 
Your blade looks fine.
Just send your knife to BM for a Spa treatment.
