I'm gona throw my 2 cents in....not to try to change anybody's mind, but just to relay my experiences. Personally, there is no place in my shop for ANY "quick set" epoxies. Some have hear my story as to why, but it's worth repeating.....
When I started out, I used "5 minute" type epoxy. About 6 years after I started selling knives, I had a rash of knives that came back to haunt me with "loose" handles. Some to the point where slabs had completely loosened, with what looked like a fine white powder where the epoxy should have been. Long stary short, I did A LOT of research, and found that all the commonly available expoy makers engineer their products to chemically break down in 5-7 years. It sounded crazy to me too, but one chemist told me that if the product he designed lasted forever, he would quickly be out of a job, which makes sense from a business standpoint. Anyway, after those experience, the only two products that I would recommend are Acraglass from Brownells, or West System Marine epoxy. Acraglass has a 10 year shelf life, and a 50 year hold life. West System marine has a 5 year shelf life, and a 20 year hold life.
I never thought much about the type of "glue" I was using, until it came back haunt me. If you're planning on being a knifemaker longer then a few years, I'd advise you to dump the "5 Min" stuff, and go with one of the products I mentioned. Just Sayin!
