The Crawdaddy tool is very different. It is loosely based on a late 19th century antique wrench tool that a good customer sent me for my collection. The antique tool had machine filed teeth and showed evidence of crude forging. I updated the design considerably and limited the sizes to just six: 1/4, 5/16, 3/8, 7/16, 1/2 and 9/16. The two holes where his "eyes" would be are sized for a bead chain for a convenient neck carry option if desired. The Crawdaddy is just over 3 inches long so it will ride well on a keychain or in a pocket too. Made of CPM 154 semi stainless cutlery steel hardened to 58 Rockwell and features a bead blasted finish.
One of the things I like about this series is that you can store any standard one inch long 1/4" hex bit that you want. So if you want Phillips you can have it. Square drive, Torx in any size, 1/8" hex if you want one for your Strider pivot, tamper proof bits of all kinds. There are literally dozens to choose from but I will be supplying a nice USA made #1 Phillips with these.
The O rings keep the bit plenty snug and the bit is accessible from either side so the tool is ambidextrous.
