I want to decorate a bowie I'm working on but
I'm uncertain which technique I should use. I have access to a paragrave
tool but I heard or read something to the effect that engraving can weaken a blade (don't know why but I don't feel like
testing it if it's more than just a theory).
I've etched circuit boards so I'm familar with the fundamentals of the process. Is this a better technique to use? Are there information sources that will help me?
Which ever technique I use, do I heat treat the blade first?

Always think of your fellow knife makers as partners in the search for the perfect blade, not as people trying to compete with you and your work!

In my opinion the paragrve system isnt the way to go. I prefer the hammer and chase method of engraving. The acid etch comes next. David Boye and his wife used to do the etch alot. Those early knives are very collectable now. Dont worry about weakening the blade. Use good heat-treating and it wont break. Bruce B.
 
If you decide to engrave your bowie, do it before you heat treat. If you decide to etch, do it after you heat treat. Whether to engrave or etch depends on the type of decorative work you chose to do. Each method lends its self to some things more than others. For instance engraving is like tooling leather with scrolls and such, etching is like scrimshaw work with pictures. I would not be concerned with weakening your blade, there are many other things that can be a bigger worry than this decorating business.

I really want to learn etching! If someone will give me a hint as to resist and etching solution I would be greatly appriciative.

I was taught to etch using asphaltum varnish for a resist, for this to work well the metal needs to be extremely clean or the varnish will not stick and the acid will undercut your design. We used hydrochloric acid for the mordant. Good ventilation is a MUST as this is a very strong acid. A strong acid will cut pretty quick. Experiment before you try it on a finished blade. www.riogrande.com has etching supplies in their tools and equipment catalog.
 
Thanks, Richard. I have the Rio catalog and didn't think to check. I'll post a pic when I try.
