Just came across this forum, figure i'd sign up and give it a try.
I think x-lock works slick, can't say for sure if they will catch on but I like the idea. Bosch invented a few quick change tools/accessories that have been adapted pretty universally. Both SDS and T-shank jigsaws have become the normal, both invented by Bosch. For OSC Starlock hasn't taken over, but I think because the universal type is lower priced and just as easy of a setup. (VHS vs Betamax) I believe the X-Lock blades can be used in a standard grinder still, providing the costs aren't much different I can see retailers changing out and just stocking X-lock accessories since they will work with both.
I suppose we will see what happens.
