i have a 975SBT and a CQC7 EKI. the blade isnt much longer on the BM, the EKI has tip up/tip down capability and some are waved, and i like the green G10 on the EKI's also. that said, i really like the BM 975 a lot, i carry mine fairly often, and its well made, imho prob pretty close (or equal) to the EKI product as far as quality. that said, neither one is my fav emerson design, imho the SOCFK is a lot better than the CQC or the 975, i like the handle better, i do think the SOCFK is better made/finished than the BM, all of them are waved,i have a green G10 SOCFK w/a black tanto blade, and its my fav EKI ('cept for my CQC8!!!!)
but, of the 2 mentioned, i like the 975 a little better, a I&I tanto EKI would be cool also imho, i have been wanting one for a while, might have to get one and retire my 975!!!
