I'm echoing everyone elses response to TSA. It varies widely by location and if the TSA goon has a bad day or not. I carried a no blade, cheapy multitool. Like a knock off version of a swiss keychain multitool, for many years. It's even been pulled out on a secondary a couple of times and they gave it back to me. It has a plier, a #1 phillips head and a small slotted screwdriver. So 3 tools.
Just last year, the bag got pulled aside again. And I already knew they were going to look at the keychain tool. The "agent" was youngish. He pulls it out, plays with it and says it's not allowed. I told him, it met the size and requirements. He said no it doesn't. It's a tool. Tools are allowed, but I'm sure this rent a cop just left training a week earlier. I'm not going to argue with this clown, and so I walked away.
Anything TSA compliant or allowed, isn't guaranteed. Be prepared for any tool to be confiscated/stolen by these schmucks.
