Not strictly true, I've been mulling this for a while now. The Knew Concepts precision saw guide... A more advanced version of the RT blanking saw. It's the v3, so it's compatible with the Benchmate which is handy both in use & for storage (I have several dovetails mounted up the side of the bench for parking tools).

Obvious uses are for cutting thick matrix dies at 90 degrees so that I can press form mirror images, as well as for cutting pancake dies in tool steel. Without a press available, it probably doesn't make much sense; with a press it's suddenly a much more sensible idea. Other uses? I've no idea, but a couple of good pancake dies will pay for themselves quickly.

Go on then - someone tell me I should learn to saw at precisely 7.5 degrees from vertical
