Penetration tests of three comparable kives

I am going to compare two knives that I personally designed and made (Bowie 10 x 330 grams a Karambit style throwing Knife that I designed) against three Vector Knives by Dmitrii Melnikov to see which one Sticks Penetrates the wood best. I am not implying all Russian knives are bad because that is all that I buy, I cannot believe they can stick knives, but the again it goes back to the species of wood they use that we do not have. I have pictures of the new set of Vectors designed and made by Dmitrii. I was surprised how well they threw, but did not stick very deep, and would be easily knocked out if another knife banged into it.
