How deep is the recurve on the 750 pinnacle?

Is there alot of reverse curve to the cutting edge? I really like this knife and would like to get one, but I don't have anything to sharpen a recurve with, and I don't want to spend $100 on a sharpmaker when I already have good sharpening stones for everything else. Is there any possibility of me sharpening it on a narrow bench stone? ( 1" to 2" wide) or maybe the edge of a stone( 1/2" wide)?
If not I'll probably get a 750s, because I do have a diamond file to sharpen serrations, it just isn't good enough to do the whole edge of the knife and get it as sharp as I want.

Hi Matt,

For about a year I carried the 750 as my fav of the rotation mix. Can't believe I can't lay my hands on one within easy reach to compare the depth of recurve but I'll still offer a comment. I never tried to sharpen it on a flat stone cause once I discovered how good I could get with a Sharpmaker I never went back. I do remember looking at the depth of recurve as I was sharpening but it never presented a problem. I would think that the 1/2" side of stone would be about right to deal with good contact thru the radius since that is about the width of the ceramics on the sharpmaker. Good luck...its certainly a fine blade for the price. They are definitely in the 'keeper box' in this household.

Matt,
The recurve on Pinnacle's blade is not too deep, it is noticeably shallower than one on Model 710 Axis Lock blade. I think you can sharpen it on 1/2-inch bench stone's edge. But if you want to do it decently - go to rod-based sharpener. Very reasonable alternative could be SPYDERCO Pro-File. Very versatile and useful sharpener for experienced user, a bit moved into the shadow with their own product - Tri-Angle Sharpmaker. You will not regret if you will buy one or another.
One alternative more - Eze-Lap Eze-Fold sharpener. It is diamond coated sharpening surface with oval-shaped crosscut, 4-inches long and it folds into plastic handle like butterfly knife.

Where did you find so scalping price on Sharpmaker? For $100 you can buy at least Sharpmaker, Pro-File, Eze-Fold and even to save some bucks for beer

BTW, I like American made knives and sharpeners but European beer is better

Thanks guys I'll have to look into some of the rod sharpeners, and take another look at the 750 and 750s. I really like the results I get using bench stones on all my other knives, and have gotten enough practice from sharpening all my carving tools that I can get most blade shapes scary sharp with them.So I'd rather not spend the time and money to learn a new way of sharpening.
I just threw out $100 as a guess for the sharpmaker, I thought I remembered someone saying the 204 was in that price range.If you say they're cheaper I'll have to look into them.
I have some small arkansas stones that need dressed because they're a little bit glazed. I may just try rounding the edges on them with some medium grit sandpaper.

Matt,
I used a lansky system to establish a uniform 20 degree edge on my 750. The recurve presented no difficulties. Since then I have used the Sharpmaker to keep the edge. It's an extremely convenient system for maintaining an edge and you should be able to find it for $50 or less. Check with Mark at MJ&S...he's just down the road in Circleville. The 750 is good value in a heavy duty folder. Let us know what you think if you decide to get one.
regards,
Phil
 
Matt, I handled a few at various stores. The recurve isn't extremely steep, and you could probably do it with relative ease using a Lansky, but it might round the edge of the stones a little bit, not that it really matters. A steep recurve will make it so that when you sharpen with the Lansky, only the edges of the hones touch the edge, and this wears the edge of the hones quickly. To most people this isn't a big deal though. Just thought you might like to know.

Also, if you are into partially serrated edges, the plain edge portion won't be "recurved" and you can sharpen the plain edged portion with a normal flat stone and the serrations with a serrated hone for the Lansky that you can buy at DiscountKnives.com. BTW, 204 Sharpmaker can be gotten at DiscountKnives.com for about $40.60.

Thanks chang
Thats what I figured on that flat stones. I have some older stones that I don't care about rounding the edges off of.
And same for the partially serrated edge, I know I could sharpen it with the stuff I have, but it gets to be a pain in the ass sometimes. Its probably worth it though to be able to cut a wider variety of stuff without switching knives or blades.

I have sharpened my 710 with a sheet of 400 grit wet/dry wrapped around the handle of a wooden spoon. Seriously.
 
Wow, Steve, what the nice idea!

May I improve it in a small bit? Let's take the round wooden handle of broom, warp it with sand paper and we'll have nice and very looooooong sharpening rod.
Seriously

Hey, how far over does the lock bar typically travel on that knife. I know there must be some variance. Just curious, I'm going to pick one up.
 
You ought to be able to get a Sharpmaker at a reasonable price, but if you think about it, you should get the best sharpening system you can. If you don't it's like getting a nice car and using bad gas or cheap oil.
 
AF,
Please look here for more info. The photo of locking device is included.
Mine lacks about 1,5 mm to travel all the way to opposite scale and I think it is quite normal. Even if the lock will be worn out (all things wear out in this world) and travel all the way to opposite scale it will no way affect lock reliability. Because locking shoulder is as thick as blade tang.
