Review on Circular Cutting Mandrel Extension AniSqui by Dean Ledet

I was excited to have these little blades to go with my ryobi twisting tool that I use on my cigar box guitars. I inspected the blades, made sure I understood the purpose, and adjusted the first blade, screwed a small screw into the mandrel and turned it in to begin the cut. Within 25 seconds, the propeller spun up and out of the mandrel, and the blade flew away at high speed. Luckily he left and not on me. After closing everything, I looked for the little screw holding the blade to the mandrel and it disappeared into my shop. It's still in the store somewhere. Due to the size of the screw I could not replace it. So I have a few small blades that I can't use right now. Like I said, it's a great concept, but the app leaves a lot to be desired. It's difficult to honestly answer the question of the durability, craftsmanship and overall value of this item. Due to the existing method of holding the blade on a spike, a small screw, I cannot recommend this item and consider it unsafe.
