Hi OIMO,

I have never handled a Vic Classic with a whistle, but Doug Ritter has here http://www.equipped.org/pro_pocket_kit.htm while testing the Pocket Pro Survival Kit (note: there is a close-up photo also).

Good idea, this knife would be a useful addition to my key chain, more multi-purpose than my Fox 40.

If you get one please give it a try and report how it sounds.

Thanks,

Mike
