[QUOTE="ez bake, post: 1859507, member: 229"] Man - a blade that small is going to be difficult, dagger-grind complicates things a bit and serrations make it a little trickier even (unless you only need the non-serrated portion sharpened). Good luck! :D Well, "shaving sharp" is different to different people. And even a knife that can truly be used to shave your face isn't considered extremely sharp in the world of knife-sharpening. If you can whittle a hair by only pulling the hair against the edge, that's pretty darn sharp. That being said, if you can push-cut printer paper, you're doing something right. If you have to slice-cut that same paper, it's slightly less sharp (or it has rough spots on the apex of the edge) There are several issues with the majority of pull-through sharpeners out there (including Smiths). 1. the angle of the sharpening-steels in the pull-through are usually well more obtuse than you would ever want your edge to be (they do this because the sharpeners are idiot-proof and this obtuse angle ensures that the sharpener only touches the apex, which would be great if you were just polishing a micro-bevel - but when removing a ton of steel, this isn't a good thing). 2. They also remove a ton of steel (the steel/carbide versions, not the ceramics). They do this by "cutting" away the edge of your knife. Thousands of years of sharpening have taught us that by stepping through abrasives from course to fine, you can achieve the perfect edge on any piece of steel if held to an appropriate angle. Cutting (or really, scraping) away the metal from your edge is trying to skip all of that time/effort by doing it the easy way. The affects of this are that any decent blade-steel doesn't like to be scraped or cut away (most have been hardened), so you get dips and peaks along the edge along with chips and torn spots in the steel. 3. They don't sharpen toward or away from the apex of the edge (since you're pulling them through parallel to the Apex and bevel). By sharpening this way, you're not ensuring that the apex is free from chips/wire-edges/blunted-spots/etc. They also cause parallel damage to the incline of the edge (see pic): [IMG]https://www.okshooters.com/data/MetaMirrorCache/i284.photobucket.com_albums_ll20_knifenut1013_Picture774.jpg[/IMG] I'd get anything from a Lansky or Sharp-maker to a set of bench stones (there are tons of Youtube videos on sharpening on a stone).
