Well as far as drilling a knife for the thong, it's your knife and by all means go for it. Just remember that you have waited several years for it to be made, the shop has spent a good bit of time making it for you and it looks good. But in less than a very few minutes you can ruin it forever. Sure it will void your warranty, but the shop might be able to fix it at who knows how much money. So go ahead and try it. Just don't come on the forum with your pictures and crying about what happened or how much your repair bill may be.oldguy
