Lol, that much I can guess. But he said that the bk9 could do nothing that the bk7 couldn't so he didn't need a 9, I was just wondering with that same logic what the advantage of the bk7 would be if he already had a bk2.
Its just a curiosity question. I have read many times that a 4-5" knife is just able ideal for a survival/utility knife. One of the main advantages of a longer blade is the ability to chop, another would be to act as a scythe. He said he does not use knives to chop and I was just wondering what, for him, the benefit of the BK7 is beyond the BK2. If his answer is, "its a cool knife and I like it." That is more than good enough for me.
For me personally I am not as fond of saber grinds as I am full flat grinds. Although I would not classify any of the Becker's as a full flat grind, some are closer then others. I was curios if this made a difference to him also.
