I'm looking at shorter blades my self, Under hand sword style, and dagger end length, so I need a blade that 28" to 29", and another 8" to 10", is it difficult to cut the blades down? I was worried that because of the inside of the blade there may be some serious finishing processes, sanding, deburring, etc., and I don't want to damage the reflective quality of the blade
Literally all you need to do is take a PVC cutter and cut it. The film will be there but just take a razor and slice it off cleanly. You might have to take a dremel and sand it down a little, but probably not.
