Was wondering what folks are using to apply or etch a logo on their blades
I've been using a battery charger with vinegar and salt mixture. It works pretty well I was just wondering if there was a more professional way to accomplish this task. I'm guessing it's already been talked about in here someplace but I wasn't able (or smart enough) to find it. Thanks for any input
 
I'm also interested in this. I'm bewitched by the perfect lettering and logos you see on production blades.
 
Salt water will never give you as clear a mark as a commercial etchant such as EX-9B from T.U.S. technologies.
 
Search for Zaphs etcher, it is super easy to make and works perfect. Also, if you want those perfect lines you need a perfect stencil. Get in contact with Ernie at blue Lightning stencils or img electromark, both will hook you up with top quality stencils
 
There is etching- in which you use a specific stencil for the design.
Stamping- traditional method of marking. It requires having a custom metal stamp made.
Engraving- allows for unlimited possibilities for marking.
 
The technique I've been using actually works pretty well. I'm using the salt and vinegar as mentioned above and a battery charger. I had my sign shop make some stencils of my logo out of vinyl. It etches nicely but I can't seem to keep it dark or black inside the etch. I've just seen some logo/makers marks that have a good contrast between the blade and the mark and also they seem to be almost flush with the blade. My comes out very sharp but won't stay dark in the etch for a good contrast.

Your problem is that you are etching but not marking. DC etches and AC marks it black. If you are electrically adept, you can probably add a bypass switch around the bridge rectifier in the battery charger and have a Etch (DC), and mark (AC) setting. Set on DC and etch for as long as needed to get a deep etch ( usually 30-60seconds), then switch to AC and mark for 10-15 seconds ( or as long as is needed).
