I actually prefer uncoated blades. It shouldn't be a problem if you keep a very thin (that is, invisible) coat of oil on the blade. Couple drops on each side, rub it in (careful!), and reapply maybe every month if you're in a humid climate.
 
I wouldn't do it. It would be better to pay someone that has the proper tools for that. Sand blasting the blade can damage the grind aside from taking the coating off.

well he had about 30 years of experience sandblasting for septa so he knows what hes doing, as for sandblasting a blade.....not so much, but he says dont worry about it. plus they have top of the line equipment there so im just gonna go for it.
 
I hope it works out. I was just saying that Sandblasting a blade and grinding are very different.
 
OK, Here is my experience.

Tell him to use the finest grit they have to blast with.

Your knife will look absolutely brand new when you get it back. Your blade will rust faster, easier than before. That is why you want the finest grit possible, to minimize this.

Also you will need to completely re-grind your bevels (at the edge) so hopefully, you own a belt sander. If so this will only take about five minutes.

I have sandblasted beat up blades (mostly Benchmades) and they all came out perfect. I even sand blasted a set of sebenza scales and they looked factory done. This is from a guy with little blasting experience.

You took the handles off first right?:D
 
i done a little experimenting with a sharpened blade one day in a buddys glass bead booth to see if a blade can be blasted without removing the edge. i found out you can hold the nozzle at an angle above the spine and not hurt the edge too bad. sand however seems to trash the edge more than glass bead and the finish is much coarser than glass bead.
 
If you have had any problems with rust in the past, be prepared for more of that on another level. -The only thing I'd sand/bead-blast is titanium or other rust proof materials.
(Hope you're well Richard.)

All good questions.

If the guy knows his sh*t you'll be fine. :D

If not, your blade could be quite rough and pitted. :mad:


As others have stated, a very fine abrasive is best.

Make sure mask off any areas you don't want blasted.


The knife in question is a good choice for this mod. :cool:





PS - I would not let one of my blaster's blast my blade,

...though I would have no fear doing it myself.
