G'Day,
Well I played again with the two blades today. I found an additional bronze washer from a MUT and added it to the Signal. The play issues I had disappeared, but the edge still rubs against the awl. I also have another 1mm washer (difference between the Signal blade and the Wave blade) but it is to big and the locking mechanism cannot clear it. Tomorrow I might go see the nuts and bolts man to see if he can help with a thicker bronze washer. The blade also rubs agains a small metal tab on the awl side, circled in the last pic, not to clear though...
So back to the OEM blade it is...
Cheers
Pete
