Members grammyd Posted February 19, 2010 Members Report Posted February 19, 2010 If you want, I pay the postage and you can just ship that ceramic blade over to me. I have re-beveled the angle on my two ceramic blades and taken them up to 4000 grit. I strop them usually one or twice and they go all night long. Now, I will say for some reason, I switch between my steel blades and my ceramics? I guess, like a good father, I want to give all of my swivel knifes enough visitation. Just kidding....it just depends for me on the feel when cutting. Let me know. What did you have to use to re-bevel the blades before taking them up to 4000 grit. I really need to do this. Quote Doris
hidepounder Posted February 20, 2010 Report Posted February 20, 2010 Ceramic blades can be sharpened but it takes some very expensive equipment to do a proper job. The problem is preventing the edge from failing during sharpening process. In spite of what many think....ceramic does corrode also, however it is effected differently that steel. When ceramic corrodes due to exposure to residual acids in leather, the suface of the ceramic begins to flake off creating a rough uneven surface. Where stopping removes the crystaline build up on steel blades due to corrosion, stropping a ceramic blade is less effective because there is no crystaline structure to remove by stropping. I know Troy West successfully sharpens his ceramics using his GRS sharpening system. I have also heard that it is possible to sharpen ceramics using some diamond impregnated sharpening steels and aluminum oxide paper, but I have no first hand experience with either. Hope htis helps... Bobby Quote

He also deals with stropping the blade as well. I think those articles were included in Leatherworkers "Tips & Tricks" but I couldn't find them....they must not be up yet. Anyway here is a link that explains sharpening. http://www.leatherwranglers.com/tips.html When it comes to selecting blades for different types of work, I think that is all about personal preference. The simple principles are that the longer a blade is the easier it is to use on long straight lines. I use a 5/8" long blade when cutting borders, etc. Conversely, the narrower a blade is the easier it is to use on small patterns with lots of tight turns. For those patterns I use a 1/4" angled blade. Most of my blades are hollow ground because I like them. For very thin leather I use a blade with a very flat ground angles which helps prevent cutting through the leather. For the most part, as you spend more and more time cutting, you will develope a feel for what you like to use in what situation. Hope this helps..... Bobby Quote
King's X Posted February 24, 2010 Report Posted February 24, 2010 I would recommend contacting Big Papa Leather. He usually sharpens my stuff initially using the GRS system that Hidepounder stated. He offers sharpening services for all leather related tools. You can mail it in and he will return it for a low cost. I learned how to sharpen my blades from Chuck/Lana Smith and Big Papa using a 'big red' jig. Paul's article is a great asset. I really like his knife. I re-angled my Leather Wrangler's blade and resharpened it with Paul's help. Good luck Quote Greetings from Central Texas! The Grain Side Up blog #TheGrainSideUp
Members swivelsphinx Posted April 7, 2010 Author Members Report Posted April 7, 2010 Hey Everyone! I thought I'd post an update to this topic. Being a cheapskate who doesn't sleep as much as she should, I haunted Ebay in the wee hours for awhile until I hit gold. I found a NIP ceramic blade from Tandy that was *probably* from the late 70's or early 80's! I'll tell ya, while it *probably* could use a machinist's touch to grind it a little, I managed to strop it a bit with red and then white rouge. It works pretty sweet! I still like my conventional metal blades too. I found a local tool sharpener who was able to handle these eeny weenie swivel blades at a *really* reasonable rate- 3.50 a piece. I can do my own stropping, I just have trouble holding an angle on a stone. Quote "Where there's a witch, there's a way!"
