I saw that a fellow Sebbie owner just recently had his knife reground to .010 by Mr. Tom. I believe that thread was in the Maintenance Forum.

What I'm looking for is the more opinions of the .010 regrind as it pertains to the Sebenza specifically.

How many of you have had it done? Why did you do it? How much does it limit what you can and can not cut? Are there other grinds (.005, etc.) that you prefer?

Those that know of Mr. Tom's work but chose not to have it done - why? Are you afraid of chipping or rolling? Do you feel that it compromises the strength of a knife known for hard use?
 
I don't know if I had mine redone at 10, I have had two done and they are wonderful. I have not had any durability issues, but I'm not a hard user.

I only wish CRK could to as well as Tom.
 
Tom reground my small classic Sebenza and it improved the cutting efficiency by a thousand percent. Excuse my exaggeration but the grind that Tom did was incredible. I had sent the knife to CRK first to have them thin the knife and they did improve it but only slightly.CRK sharpened or thinned the knife and sent back to me on the same day the received it and they paid the shipping. This Sebenza was S30V steel and was a brand new knife.After reading about Tom Krein on the forums I sent it to him and he improved the knife beyond any of my expectations. That was in NOV of 07. I have used the knife for my EDC and it has held up great. In fact I have not evened sharpened it yet but due to the thinner edge I will be able to touch up the edge with out any trouble. BTW, I have some older Sebenzas with BG42 steel that cut great and do not need to be thinned. I think the newer knives have a different grind and it may be due to the S30v steel.I still think CRK make the best folder on the market but they need to improve the grind on the blade. I have placed an order with Tom for 2 of his knives because this man knows how to make a knife to cut with!

A couple days ago I sent Tom my large Micarta Inlay Seb with serrations for the .010 regrind and I will report back on how I like it. I know that Tom doesn't keep the convex edge. I suppose that the thinner blade will be less heavy duty than stock and no I won't be "testing" the blades hard use ability.
Tom did work under Bob Dozier for a few years and Dozier is known for his really sharp blades. I have a large sebbie that Tom sharpened for me and have sent him various folders that he has done a great job on. I have to agree with all the above posters that IMO sebbies coming back from Tom's shop are screaming killer sharp. I expect to be very pleased when I get my regrind back, hopefully in less than two weeks.:thumbup::p;)
 
Tom's work is superb, i dont have a Seb done by him (yet) but the EKI i had done is amazing. il be sending him a few more blades in the near future, i think my small Seb will be one of them :thumbup:
 
Wow. It looks like everyone is in favor of the regrind. Everyone that has had it done, did you stick with the .010 grind?

Has anyone considered the regrind but decided against it? If so, what made you decide not to?
 
I think that once you get the .010 regrind there's no turning back. I think Tom said CRK cuts it at about .030. My hypothesis is that CRK leaves a thick convex grind for two reasons. It's better for heavy duty use and it also leaves the option open to people if they want it sharpened differently. It's also a liability issue. If CRK grinds it down and the customer isn't happy, said unhappy customer will cry for a replacement blade. If Tom grinds it down and the customer doesn't like it, the option of getting a new blade (and I've had it done) is there but it will cost the customer. I strongly believe that Chris makes every detail of his knives for a reason. If the end user desires to modify, then it's on the customers dime, not CRKs. I think that the convex edge is sharper and more servicable than the straight v grind edge. I think that most people won't try to run a $400 pocket knife through a car door to see how tough it is.:cool::thumbup:;)
 
I agree with you Scott, it's just frustraiting to have to send a brand new knife to be sharpened. (Or do it oneself) I thin CRK could make them at least as sharp as a new Spyderco without problems.
 
I completely agree, Dave.

Well Scott, you talked me out of it. If I can't run the knife through a car door, then I'm not interested. :)

No but really, I'm not seeing the negatives of this regrind. I'm sure there are some, but the benefits appear to outweigh them.
 
Tom reground my HD-7 to perfection. My sebenza S30V is super sharp and I'll keep it the way it came. But, if you want a cutter---send your Seb to Tom. My "7 "is my sharpest folder and it is on par with my Leu custom kozuka. Now that's Sharp!
 
357---Make sure you ask Tom about the grind! My Emerson has a slight hollow grind on it.
 
One problem with a hollow grind, I think, seems to be that if you are slicing down through something, the thinner part of the blade above the edge isn't holding
the material being cut, apart, like a wedge. The material is allowed to come together a bit and tends to pinch the blade near the edge. Also, when the material
runs into the upper part of the hollow grind, the contact angle causes more resistance than a blade with a flat grind.
 
357---My point was; Tom will recommend a grind to you for your knife and your needs. He can do any grind you want! I told him to grind my HD-7 the way he would grind his. My HD-7 is for Serious use only. I should have been more clear.
 
Thanks, Lycosa! Tom certainly does nice work.

Just thought this picture was interesting. I've not used the blade in the pic below (an extra), but have used one of my other Mt Mini SOCOM Elites FLs quite a bit and it cuts very, very well.
It is a flat grind and looks much like the photo of the Sebenza blade reground by Tom.
