Don't put your nut tool or knife in with your gear, and you should be ok. I try to get all the heavy stuff in my carry on, so that my check-in bag will be under 50 pounds, and I won't be charged extra. They will usually look at your gear after it goes thru the xray, but thats just standard proceudre. Just don't put your nut tool in your carry on, or you will have it confiscated!
