Sharpening?

If you want to do a convex edge, that will be polished. Get a bunch of grits of sandpaper going all the way up to 2,000 and then use a leather strop with green compound and a mousepad.

I sharpen this way and I'd put the hair shaving edge it gives against any edge a system costing 200-300 will give you. However I am talking free hand sharpening here, so practice the method before you go sharpening your favorite knife.

You can also get a convex edge with freehand sharpening and paper wheels. Its just understanding edge geometry.

If one understands edge geometry and what is required to bring two edges together you can sharpen any knife or sharp tool with a file and a steel rod that will give you an adequate edge that can split a thumb. This happened to me.....twice!

Here is an edge I finished up after last weeks EDC.

Sharpened initially on 320grit sandpaper, 600grit diamond paddle, 1000 grit lansky UF ceramic, then I am fortunate to have the Spyderco UF Benchstone with me as I am away from home for the past 2 months, and then LIGHTLY just knocked the burr off with 2-4 strokes on a small field strop. It is slightly convexed.

Now though I sharpen the edge up to this degree maintenance throughout the week is done on 600grit diamond stone as I feel this gives me the best working edge (sawing motion through material). Or, depending on how I feel the edge has performed just on the Spyderco UF stone (pushing through material like working with wood).

There really is a LOT of info on the forums to read regarding sharpening, edge geometry, different grits and their affects due to carbide formation etc. It just takes time, resources and a attitude of sitting down and reading the stuff to get educated that will yield the best results regardless of sharpening system.
 
How good of a mirror polished edge would you be able to get with the sharpmaker?

A few guys on the spyderco forums said it's nothing close to what edge pro gives or wicked edge...

Some guy on youtube said it's good enough, and to just finish with stroping with an added compound to make it shiny.

Please share your experience. Thanks!

On the sharpmaker, after your initial sharpening on the brown and fine stones. Use the ultra fine stones ( must purchase separately ) and it will polish the edge quickly. There is vast difference between the fine stone white stones that come with the sharpmaker and the ultra fine white stones. If your looking for a polished edge, they are well worth the extra $$.

Here is the polished edge I put on the SMF I used to have. I haven't done it to a sebenza yet though, but you would have the same results. When I reprofiled the SMF, I finished it off with the white ultra fine stones. I wish I could provide a better picture, but I sold the SMF recently.

Looks dam good to me ^ The polished edge is not the only thing I'm after, but I'd be lying if I said I wouldn't want it on my knife.

If it really came down to function or aesthetics, function would win out every time, at least for me. But why not have both =P

Can't wait till I get my Sharpmaker, my sebbie already feels on dull side...

Thanks guys!
 
Dont forget, you get diamond rods now for the sharpmaker to reprofile with. Will make the process much faster.
 
Best advice I can give you is to learn what a "burr" is...Study it...as will save you a lot of frustration and uncertainty in wondering if you are reaching your goal in sharpening effectively....once you get that concept, and can learn to form it evenly on both sides, and then subsequently remove it, it is likely that whatever method you use as long as you keep practicing, will get the knife sharp, and the more you perfect it, the longer your edge will last, until you reach the blade's full potential.
Techniques can vary getting to the burr phase, and also afterwards in final polishing. With different techniques, come different results.
Good news is some of the more reputable guided angle sets come with insructional DVDs, or there are many good resources on youtube etc.
The razor edge book of sharpening really helped me to learn about the burr, and the entire process of sharpening but as I said, there are many great resources.

Now, down to tools..Freehand man myself, typically a DMT or a EzE-Lap to do any major work on the blade, and then move down to fine grit carborundum then to ceramic, and then I have an old superfine stone I found at my grandpa's (almost like slate?), real easy to see if there is ANY wire edge (burr) remaining. Once done with that, just use a strop for polishing/regular maintenance. - that's a lot of info to throw at you, but as you have seen from this thread, there are many, many opinions on what works best. - The important thing is that you have some type of coarse (rough) grit stone to pofile an edge, and a fine (smooth) grit stone to polish an edge - you can get a dual sided norton and be ok, without dropping a ton of $..at first anyway:-)If you are new to sharpening, and have not settled on a method, the sharpie trick is a great way to make sure you are taking steel off where you want to, and that your grinds are as even as possible until the burr is formed etc, But, if you are new to sharpening altogether, practice on a knife, or several that doesn't/don't mean that much to you until you get a method that works.

Personally, I would reccomend to that if you feel uncomfortable or hesitant in learning to sharpen freehand at first, or if you want to make sure your edges are as perfect as possible, and there are no scratches on parts of the blade you don't want them on - go with a guided system like those that have been mentioned. You may end up sticking with one for good, and is a great way to understand different angles and what they achieve when done correctly..Then you can learn freehand later for use in the field etc until you can get back to your primary set up.

By the way, please don't take my suggestions as that I think I know everything..have just spent a lot of time trying to figure out how to sharpen properly and get the most out of an edge between sharpenings and have experienced mixed, frustrating, or poor results in the process, until, an old friend of mine taught me about the "Burr"..;) which, btw, is a concept we need to understand clearly whether we used a guided set with fixed angles (Edge pro / Lansky etc) or do it free hand...Good luck and have fun! Once you get a Burr, your almost home, it's a guidepost in the process of getting from dull to sharp.
I'm still learning and looking for ways to get the most out of a blade's potential, as well as my own - it's fun to learn.
