The basic apparatus goes back to 1890 but it has been manufactured in modern materials. A stainless steel blade and wooden handle which matches exactly our standard knife thru’ arm make this piece of apparatus you will be proud to own. This knife is a perfect follow up to our standard Knife Thru’ Arm and we supply details of how one knife can be switched for the other without using too much apparatus. This knife enables you to run the knife through your arm and then slide it up and down your arm rather than cutting across the wrist as with the standard version. It will also squirt blood whilst you are sliding the knife up and down your arm. Due to the support wire being painted red, it is possible when blood has been squirted, to show both sides of the arm if working a reasonable distance away from the audience. PLEASE NOTE: this knife matches OUR KNIFE THRU’ ARM but it does NOT MATCH any other dealer’s knife thru’ arm so there is no point in purchasing it to switch with any other make than our own.
