Does throwing Technique make a difference

I decided to make 6 more knives, but got sidetrack because my cat lost in top of the house, so I spent 3 hrs finding him. Now, I am going to prove once and for all that a 154 lb 73 year man can stick a raw cut of steel that I am going to make six knives out of today. This is proof enough for me, and if you cannot accept the truth, then to bad. Every time I have to modify a knife to stick in my wood targets it make everyone made, well don t bother getting a knife and fork because you are going to eat Turkey and the feathers. I cut this blank out and it is 6mm x 22. 8 cm long, thrown from 2. 5 3 meters and penetrated a hardwood target, not Poplar like you have access to in Russia. Yes, you can get a Poplar wood here, but it has been Kiln dried and treated and it is hard as hell, My target back was going to be my target when I built 4 years ago, Now I mount hardwood rounds on to throw at. , There is a big difference between 500 550 gram Rotational spin versus nospin, almost 1, 2 the weight.
