FLHWP: Custom WhistlePopper
Brian Fellhoelter Custom Knives
The WhistlePopper. What on earth is it? Well, it’s a whistle AND a bottle opener. And an extremely LOUD whistle at that! It’s made out of 6Al4V titanium, comes in around 0.25" thick, 0.75" tall, and a little less than 2.5" long. The whole thing is held together by two custom-made titanium screws. Though is very minimalist looking on the outside, there is a surprising amount of detail inside, and each whistle takes almost an hour to machine!

Nobody's EDC is complete without a whistle and an opener, so, you might as well kill two birds with one stone. Get one for your keychain now. Might as well get another to use as a zipper pull on your pack while you are at it.

Super workmanship
I just received my WhistlePopper. I took it to my shop to smooth any rough edges with 2,000 grit wet/dry sandpaper so it wouldn't tear my pants pocket. Well, there are no rough edges. It is smooth, small and light. Just what I wanted to add to my house keys but not make them feel too heavy. It is a superb piece of workmanship and very loud .
