Commercial is allowed exclusively for Greyhound Lockpicking.

I used a tongue and groove design unlike most other picks so that it will fit multiple thicknesses. This fits .015-.025 picks that Greyhound lockpicking sells. So one handle for many thicknesses. 

There are 4 total models

2 Short for fitting into lock picking bags

• ~6.3 X 2 MM magnets of the ¼ x 1/16 inch commonly used by 44delta handles
• 6 X 2 MM magnets commonly available

2 Long for comfort use

• ~6.3 X 2 MM magnets of the ¼ x 1/16 inch commonly used by 44delta handles
• 6 X 2 MM magnets commonly available

I friction fit them I use a rubber mallet and a bit driver extender to push the magnets in make sure they are flush or below the tongue and or groove otherwise handle may fit funny.
