Hey folks. Jake and I have been watching "FIF Knife and Death" together and he has become interested in throwing knives, which is something we could set up in our smaller back yard. Naturally, I went to Amazon and looked a bit at some sets and their reviews, but I was wondering if there were any major pitfalls to try to avoid before spending the money on some. I have no experienced with these and have no idea of what I am looking for. Just FYI this is one of the sets we were looking at. https://www.amazon.com/Smith-Wesson...pID=51zr6CODAHL&preST=_SY300_QL70_&dpSrc=srch Thanks in advance for your anticipated excellent advice.
