Well, the cats out of the bag now. I have been keeping this one to myself. The problem is they are difficult to do but not impossible.
Sal, I have just one of these and its the one I put on my Blue Rescue. If you are interested in seeing it or the whole knife it is mounted on that isn't a problem. All you need do is ask.
I just thought I'd throw that out there in case you are watching because these have to be the number one requested low rider that I get asked about making. Seems that at least once a week someone is asking me if I can do one of the barrel type pocket clips in a low rider style for them. I got another request just tonight and finally fessed up. Up until tonight I have been keeping this one a secret but with very good reason.
The fact is I don't think I can meet the demand for these for several reasons. One they take far longer to make, and two they are problematic for me due to the hole size. I simply have small equipment. My drill press is a mini so the hole for the big head of the barrel bolt has to be drilled out by hand since my drill won't accomadate anything above a 1/4". Not a chore I care to do over and over again by hand but maybe one you could with your state of the art equipment???. There is also the problem of making a low rider go into a recess cut out. The fit has to be exact or there is the potential for wobble back and forth since there is only one screw/bolt holding it in place.
Anyway, your call.
