The Emerson CQC7 (as well as several other Emerson models) has a 'wave' on the top of the blade which allows it to be opened as it is removed from the pocket. This is done by catching the wave on the pocket opening. Go to 2:30 in this YouTube clip -

I was web surfing yesterday and came across a company that makes a device which converts a thumb stud into a wave -

I have an Al Mar SERE 2000. To convert remove the thumb stud and insert the device into the hole and tighten. Now here's my problem. This is a very expensive knife. I guess - but don't know - that the stud simply unscrews just like a nut and bolt however I've seen examples of knives that have the stud expanded into the hole under pressure. I don't want to ruin it and irritatingly, Al Mar doesn't have any telephone number for tech questions.

Any advice?
