After doing much research I decided to buy a cqc 7 with wave feature..after checking a couple of sites i noticed they weight was different..some said 4.0. oz.some had it at 3.8..3.5..so I called emerson directly and asked them what a cqc with wave weighted in at...the lady who answered told me to hold on she said she would take one out of the box and weight it for me...When she got back on the phone i was told with the box and paper work it weighted 4.0oz..out of the box by itself it weighted 3.5...sounded great to me since I wanted a knife under 4oz...so I ordered a new 2012 model cqc 7 w/wave....but when I opened it up it felt heavier than 3.5 oz..so i weighted it on a friends digital scale and it reads 5.0oz wtf is that about? I know they make thicker ti liner now but did that add an ounce also the women who weighted it for me at emerson I would assume was weighting a 2012 model??? I found a youtube video of someone weighting emersons on a scale and his cqc 7 was 4.4 oz ..emerson has it listed on there site at 4.oz..no where near the weight of 5oz that i got..whats up Emerson????
