See my other listings for more Friday the 13th Jason Voorhees items signed by Ari Lehman, including certificates of authentication. Take a look at the last photo and see that the machete knife has always been kept dust-free in a display case in a smoke-free, pet-free home. Lots can be shipped together, which saves you costs. Here I'm offering one machete knife in very good condition from the horror film Friday the 13th, featuring the character Jason Voorhees played by Ari Lehman. Signed by Ari Lehman with certificate from Prestine Authenticatic. I will carefully pack this item and ship it insured within 2 days after you are the lucky winner of this lot.
