Would this effect work with a small pocket knife, like a Classic 58mm Swiss Army knife?

You would probably have to modify the handling since the blade doesn't pop out.

Stab Happy

The classic card stab effect has been re-designed for close-up and street magic performers.

A card is selected, signed and returned to the deck and shuffled. You then pull out a knife, stab it into the edge of the deck and pull it out to reveal you've impossibly stabbed their signed card.

Stab Happy is a SUPER EASY to perform version of the card stab. It can be done with almost any knife, or even a borrowed knife (although the latter will require some slight preparation before you begin).

You'll get both a Blue and Red Bicycle Rider back gimmick that comes ready to go out of the box. As well as some extra materials to make extra gimmicks that can be fitted for almost any custom deck of cards. With a little practice, you'll be ready to perform Stab Happy in no time.

There are even ways to perform this without a knife by using other objects such as a playing card. You'll learn everything you need to know in the included instructional video.

IMPORTANT

You DO NOT receive a knife with this effect. You must provide your OWN knife. Please use care when handling sharp objects. Keep them away from children and do not cut towards your fingers or your body. Vanishing Inc. Magic cannot be held liable for any injuries sustained while performing Stab Happy.

Customer reviews for Stab Happy

Roman

This is an excellent effect and overall I like it very much. Just be aware that you are buying just the effect, not a whole routine. If you want your routine to be deceptive enough, you should add a few very basic sleights so that the spectator believes that his card is really lost in a pack. These sleights are not taught in the video accompanying the trick. Fortunately you can find many tutorials online (including versions for beginners).
