I wish there would be two things as far as riving knives go.

1. A standardization on the table saw. Easier to change, remove, and adjust. It should be as easy to change the riving knife as to change the blade.

2. Riving knives in various thicknesses. Using a full kerf 1/8 inch blade you have a 1/8 (or slightly thinner by a few thousandths) riving knife. A thin-kerf blade of .098 would have a compatabile riving knife. I often use a 7 1/4 circular saw blade in my table saw and it needs a .055 riving knife. Since there's not a riving knife available with my zero clearance insert, I use none though there is a slot for a riving knife.

While I rarely use the blade guard, I always use a riving knife except with the 7 1/4 inch blade. Those who are aghast that I would use the 7 1/4 saw blade on my table saw without a riving knife I understand, but this is not the thread to point that out.

Any ideas? Does anyone make riving knives in various thicknesses?
