I bought the funxion emt model. It seemed like a great knife but with less than a week of very light use the blade no longer locks when it is opened. The company is more than happy to repair if I pay shipping to send it to them. Or they said I can return to the place I purchased. Since I purchased from mass drop however that is not an option. So apparently I am stuck paying for shipping charges and waiting even longer than I already have. I guess that is the catch with Massdrop.
