Here is a relatively inexpensive illusionette that can be performed on your assistant or even on yourself. Disarmed can be a pretty shocking effect if done properly but there are a couple of concerns with this effect.
The angles are critical, you must be very careful with angles not only left and right but up and down. Also, a small bit of acting is required on your part to pull this effect off, and finally as with almost all chopper type effects for arms and hands, this effect will work better on people with smaller arms (same can be said for torturette, disecto, etc).
This effect is very easy to do but you will have to practice to get it right. When showing the effect the separation should be done quickly to add to the shock value of the effect. As with other chopper effects, a touch of red paint on the blades adds to the authenticity.
Force 2 Solid metal Blades thru your arm. First you ZIG-ZAGGED your assistant, then SAWED her in two, IMPALED her and CHOPPED OFF HER HEAD. Why not mutilate yourself for a change? Place your arm in this box and show both sides. Now slowly insert the two aluminum blades through your arm. Unlock the latch and open the box! Close and lock the box, now remove the blades. Is your arm in tact? Indeed it is, and the box is left completely examinable.
The Cabinet opens on hinges and separates your arm in TWO!
