RE: PROP TOOLS
It's funny how we do things differently, depending on what your're going after. For .36 size C/L combat, you buy your props by the bag load and simply [and quickly] sand some length off the blade that is heavy, ending up with uneven lengths that run just fine at 20,000.
For a prop that has a 2 minute life expectancy, it is too much work to do it the right way.
