PERSONALLY I don't think that the wave feature is a good fit for all his folders. For SD knives yeah they are a GREAT addition. For like say the cqc7 and others that I consider work knives I think thy just get in the way. Yes this is just my opinion, but take the Fixed karambit for example. It has the Wave feature and to me it is totally useless and is there only to make it look like the two folders and serves no purpose.
