Thoughts about Krein regrinds on CRK's?

[JTR357]

I have a Large Classic Sebenza with blackwood inlays(which I LOVE BTW!)
I've been thinking about sending it in to Tom for a regrind.I'm just not crazy about the original hollow grind & feel I can get better performance from a FF grind @ maybe a 30 degree inclusive angle.

Couple of questions:

1.Will it void CRK's warranty?

2.Is it generally frowned upon to do this?Why?


Thanks

Personally, if youd like a regrind, do it. I did it on my bm 710 and wow is it a laser. I think it would be awesome on a CR knife. Something I would consider.

Yeah,I got a Kershaw S60V Blur(blem)reground by Tom & it's at least twice as good as it was before!

I believe it does void the warranty as it applies to the blade. Tom reground one of my small classics and I'm very happy with it.

Here it is....

Mmmmmmm FFG Sebenza. One can only dream.
As for the warranty, the blade would probably be no longer covered. But as for the handle and everything else I think Chris is understanding enough. For bigger manufacturers it'd void it probably completely.

Thanks for the comments guys.

I'd like to hear if it voids the warranty completely from a CRK rep,if that's possible.

If it does,I won't do it.If it just voids the blade,I might.

I had a small BG-42 Kreined a while back, I did like it but the belly was ground off a bit. Not Tom's fault at all, I wanted a thinner hollow grind... so in order to do that you remove steel.

It just got to me because it looked different from the stock belly shape. If you have ever seen a well used and sharpened sebbie, you'll see it loses it's belly along the years.

Cut great, but I sold it because I'm a weirdo

Why don't you like the hollow grind?

I feel it's the best grind there is for many reasons. One being as you sharpen it, the edge stays thin. Unlike a flat grind as you sharpen it, the edge gets thicker and thicker.

Also there is less friction when cutting something thick, or say cutting a block of cheese. After the blade cuts, and you pass the shoulder of the grind line, there is a air pocket between the blade and what your cutting. That's because the hollow grind is scooped out. A flat grind, has the full sides of the blade contacting what ever your cutting all the time, making much more friction.

I feel a high hollow grind like the sebenzas, can cut better and is just as strong if you ever need to pry with it.

Not drilling you Just wonder what you don't like about the hollow grind

It's just a personal preference So-Lo.I don't hate HG's,just like FFG's better.Their easier for me to touch up,for one thing.

Tom reground my Small Classic Sebenza and it cuts like the afore mentioned lazer. Before I sent it to Tom it was a so so slicer and cutter. It is amazing how Tom's reground improves the Sebenza and I would not worry about voiding the warranty. Just treat your Sebenza with respect and do not abuse it. And you can call or email chris about the warranty. BTW, I have an older Large Sebenza with BG42 ateel and it has a much better grind read thinner and it cuts as well as the Tom reground Sebenza. And it came that way from Chris. I think when Chris went to S30V he left the blades thicker at the edge. I think Chris needs to rethink the thick edge on current Sebenzas as my Spyderco and Benchmades are better cutters and slicers but The Sebenza is still the best knife Quality and workmanship I have ever used.

Have you set your own bevel yet?

I only ask because you said it's harder to touch up, you may be using a sharpmaker on it, and not getting great great results? CRK's edge is slightly convex. So a sharp maker will hit the shoulders, and not the edge untill you take a course stone to it to get the bevel flat. (Spyderco's and Benchmade's bevels are flat frm factory) I also lay the edge back, so touchups are only really touching up the micro bevel.

Just trying to help

CRK produced some Flat Ground Sebenzas, but they were limited and are now hard to find. When you do find one it always fetches a premium.

:thumbup:Thanks So-Lo,That explains a lot.I've never had any problems sharpening any other(with the exception of Queen Cutlery!:grumpy:,but that's another story) hollow grinds or flats,but now that you say their edges are slightly convexed...well it all makes sense now.
I really need to graduate to freehand already,like you did.Soon...very soon.



I'm gonna do it!If it can improve performance on an already perfect knife,then WHY NOT??I don't think I'm gonna get the Krein stamp on it though.

Thanks to Tony8179,So-Lo,RKH,Creepo,morrowj_98 & Thalestin.I really appreciate the helpfull feedback.:thumbup:

It just irks me when I'm looking for the right knife for the job,I automatically reach for the spydie,kershaw,benchmade or al mar when I need a slicer.When all the time it shouldn't even be a question.I have a Sebenza!The knife all other production knives aspire to be!

I think you will love it


Infact I have even thought about buying a second blade, so I can decide if I want beefy or razor blade Please get us pictures

I would never alter a Sebenza. But... if you have to, Tom is the one to do it.
