The Black Ops Kalaj Kutter Replica Tomahawk is a great tool for the beginner, intermediate, or advanced practitioner of defense (/offense) tomahawk training. These tomahawks are hand crafted from a solid piece of High Density Poly, a high impact strength and high density polyethylene which has excellent tensile, energy absorption, abrasion resistance, water/ salt resistant, and resistance to stress cracks, so you will be sure to enjoy these Kalaj Kutters for years to come. It should be understood that every Kalaj Kutter is hand crafted, so there will always be slight differences from one piece to another. I did not design the Black Ops line for contact training, or for throwing, but they sure can take a beating
