    Sharpening a double-edged,, recurved blade?

    Gents in a bit of an impatience purchase whilst waiting for my custom pig sticker to be finished ( Long story, no-one's fault, etc.) I bought a Muela remate knife from the unlikely source of Woody's gunshop of Wembley. This was a bit of significant find as there aren't many places in London where one can walk into a shop and examine a knife.

    The knife itself was the 24 cm stag horn remate knife a la:


    It's a rather nice knife, not perfect in terms of fit and finish but still manages to give the impression of being reasonable value for money through it's sheer size.

    It is the first double edged knife I have owned and although for a rather specialised purpose, this one will be used in a month and three months time. The only problem is the edge it has arrived with is rather blunt. It is hollow ground to a bit of a thick edge, left thick for durability I presume, with a edge bevel of about 25 degrees. It has a sort of large "micro"bevel at a much steeper angle though and I suspect this is behind the apparent bluntness of the blade.

    I am a Lansky sharpener for my other knives, from small to large and can get pretty good edges with my collection of stones but having a play with this knife and the Lansky clamp it is apparent I will not be able to sharpen this knife on the Lanksy at the crucial tip of the knife.

    How does one sharpen a knife of this type gents?

    All tips much appreciated.

    They are a bit of a PITA to be honest, the easiest way is to use wet and dry on a curved surface(rolling pin works well. Otherwise a rod system like the sharpmaker would be good. Recurves are tricky to keep your angles all neat.

    Re: Sharpening a double-edged,, recurved blade?

    I was worried that the answer would involve freehand sharpening at some point, something I'm not very good at and don't want to learn on this knife...

    Are there any cheap recurve blades available to practice on?

    Ask Longstrider for an estimate. Given the intended use of this blade, it may be good to get a proper job done on it.

    It's looking that way isn't it?

    I have rung Ian and he has given me a very reasonable quote to have it sharpened.

    It does bug me to own a knife I can't sharpen however...

    Once uncle Ian has worked his magic it will only need stropping as and when necessary.

    I feel a little dirty admitting defeat so easily but it really is like having a sharpening Uncle who makes it all better when you get stuck.

    I'm having a special strop made for exactly that purpose Zorro, it's going to be slightly convex to stop it being torn up.*

    Re: Sharpening a double-edged,, recurved blade?

    I don't tend to get on with recurves given I prefer to use stones, though I'm sure some can sharpen recurves on stones, I'm just a bit crap. I do really like my little Kershaw Blur recurve though, which I think is 440A. I just spent a while reprofiling it on the Lansky croc stick (long time) as the edge angle was so large the croc sticks were just grinding on the shoulder rather than edge. Strops up nicely now.

    Yours needs something a little more 'industrial' it seems! It's a massive knife that.

    (The Blur was boght as a tester for recurves, for a very low number of beer tokens. Camp out in the classifieds for a cheap recurve. There's a CRKT HAWK DOG up at the moment for not too much, which Longstrider turned into a recurve)

    Perseverance and tenacity. Just two of many qualities I am sadly lacking......................

    A Longstrider convex strop, from the master of the convex edge. There is an almost mystical symmetry at work there....................

    Thank you Hugh.

    I had considered borrowing my mate's sharpmaker but was worried on two fronts, firstly that I didn't want to be learning to use the thing on a "nice" knife and secondly they apparently notorious for rounding tips.

    Ian pointed out the many problems with sharpening recurves during our phone call and I am in doubt it's beyond my skill level.

    I am grateful for the tips on a good practice recurve, I will investigate.

    He's a victim of his own success; whenever anyone on the internet comes across something they find is too hard to sharpen they ring Ian up and tell him their woes. The conversation always ends with "Yeah I've got your address Ian, I'll send it along"...

    To the hones Longstrider!

    One of these would be good to practice on, cheap as chips.

    An interesting test project, it's certainly cheap enough to not be precious about.

    I would worry slightly chopping with a folding 4 1/2" Kukri, more so if in company.

    does anyone make DMT style hones but with a convex side as well as a flat?

    It would seem the perfect tool for the job as I' worried about buggering up the tip on the sharpmaker.

    If Ian is making you a custom strop have him make a second wood blank without the leather and you can use the wet and dry with it!

    A good idea Yossarian.

    Still need to practice my freehand sharpening before tackling this beast.

    Would putting the W&D on the leather strop not help maintain the convex edge though?
