You will lose alot of tips if you use somthing sharp . Anything that can inbed in a tree - will . I stuck a G5 small game head about 2 1/2" into a pine . Thats plenty deep to never get it back . Broad-heads will have worse problems . I would suggest using "bludgens" . These are the cheap hard rubber or plastic tips . They're durable , don't get stuck in trees , sheds , fences , etc , and are only about $9 for 4 .For small game , I use those and the G5 SGH tips . Good luck .
