yeh I did notice the groove in the middle of the block that is the only thing missing from my block but I can hold it firmly enough with my thumb up against the side and you don't really need much experience to understand a decent 45 angle.... did you design the block for genesis deano? if not you should of patented it if there isn't already one out lol nice idea
I just bought a Genesis metal mitre box a couple of weeks ago (CTD about £3). I thought to myself this will last a couple of years! Deno, I now have to invest in your design and put my metal one in my spares bag! Nice design and well done. Sean
