Ok, Tom. Take the extra time to do it. Do you have a copy of the Blade article? If not, I can scan it in and send it to you.
I'd recommend starting with a gentle, even and quick etch first. Then, after you have seen the results, do a heavier etch. Go ahead and etch it several times to get a finer, deeper finish.
Most importantly, though = tape up the guard very carefully...
That mustard will tear up the brass fast. In fact, you should probably cover the first 1/8" of the blade (starting from the guard) anyway, in case of leaking, etc.
Best tape to use is that Blue masking tape. I got mine at Home Depot. It's not as sticky as regular masking tape and won't leave a gummy residue. This is important since you will be leaving it sit for long periods of time.
If you have any other questions, please let me know.
Dan
p.s. mamav - hope this is o.k. with you. Tom said he'll ship it out on Tuesday.
