So my Cumaru bokken i bought awhile back has its review for customer service reasons. Now it’s time for a product review. The bokken has it’s strength on par with super bokkens (50 inches with about a 3/8” blade depth augmentation, whereas this is only 1/4” augmentation). Anyways, i could never see the growth ring pattern (hard to discern on an exptic wood like cumaru), and as it turns out it met my picky desires a long while back, i just never looked well enough. But its strength and resilience has earned it a very nice spot in my collection, and the sword has dealt with me outside under torrential downpour a few years back for almost an hour of full exposure and holds even to ths day. Long story short, Dan is probably one of the best that deals wih exotic wood on a regular basis.
