Here's a review of the Bamboo 150 i thought I'd post. This stone is easily my favorite coarse grit stone.
That Bamboo 150 is incredible! So much faster and less messy than the Shapton Pro 220. Reprofiling made ridiculously easy. Cpm m4 was no match. Truly look forward to more of your products in the future. Also, your videos are both entertaining and highly informative. Thanks for all the great stuff you're putting out. "
