First off, this is not my idea, but I made my first one today and thought it was worthy of discussion. Back in May of 2006, Knightrider posted THIS about some mock-ups he did while waiting for his items to arrive in the mail. I thought it was a fantastic idea when I first read it. Up until now, I never had a reason to do one. But now, I am trying to decide whether or not to purchase a rather expensive item for my keychain. Berkeley Point has this Titanium Fixed Bail Snap Shackle, which I want to use as a replacement for the cheap little carabiners that I've been using for years. Since it is a bit expensive, I wanted to make sure that it's form and function would be acceptable first. So, I printed out the picture of it, then reduced it on a coppier at work until it was the actual size, then cut it out. Here is my current keychain set-up: Here is the mock-up: Almost looks real, doesn't it? Anyhow, it looked real enough to help me make a decision. I just ordered the the new snap shackle Thanks for looking, Dan PS. Remeber Berkeley Point has a 10% discount for EDCF members.
