NiffinHey I'm really sorry for not replying back. I usually recommend these as peoples first knives to throw: https://www.bladehq.com/item--Condor-Dismissal-14-Throwing-Knife--16739
They are 14, and a decent weight, so they work well at various distances. They are also comfortable to hold for most people. I've shown hundreds of people how to throw and when I give people the choice of knives, more people choose these than any others that we have in our selection. Once you get serious about throwing, hit up Facebook and join some knife throwing groups (check http://www.ikthof.com or https://www.akta-usa.com/).
I recommend something like this if you ever go to competitions: https://algonquintradingpost.com/product/wolf/
