I have built several RC kits before and I only used the L hex wrenches from the hardware store. I would be able to complete the kit builds, but my fingers would hurt after a while. Now, I have invested a little bit of money to buy the proper tools, since I have 3 kits that are waiting for me to start and finish. I have one TLR 22SCT kit and two TLR Ten-SCTE 2.0 kits. I will certainly enjoy the builds better, using my brand new MIP Thorp hex wrenches. I only have six of them thus far, but I don't usually use the other sizes. I bought the 1.5mm, 2.0mm, 2.5mm, .050, 1/16", and 5/64".
