154cm and VG10 are my two favorite steels. Why? Because they are easy to sharpen and have resonable edge retention. I recently got a BM 710 with a D2 blade. I have tested it out pretty well. Green wood, cardboard boxes, paper, plastic banding, denim, hemp rope, nylon rope, 10 foot of carpet, pine 2x4, an old seatbelt. This has not been a long term test but it has been a good test that I have put other steels though before. Results - This D2 has held up really well. For a sharpness test I come back to a 3x5 index card as a standard. Also the hair on my forearm. So far the 710 D2 has held an edge better than any steel I have tested. Still have not attempted to sharpen it. I may or may not be dissapointed after I have to sharpen it. I admit that I am not a sharpening expert.
