Getting back into training

[Rolox]

I focus my training on open hand and crushing strength. Back when I first joined this forum, the recommended minimum gear for general hand strength was something like barbell, axle and grippers. Is more gear recommended now?

My old gear:

1. Axle bar (PDA Titan - 2.5 " grip diameter)

2. Grippers (HG150 -  HG300, Ivanko Super Grippers with 3 & 4 spring)

3. Fat Dumbbell Handle (Brute Strength 3" handle)

Recently I have added the following:

1. Rogue Deadlift bar for finger rolls

2. Spud Circus Dumbbell (this is a shortened Texas Power Bar)  + Fat Grip Extreme (~3" when installed)

3. Rogue calibrated plates

Any sort of pinch device and anything resembling a sledge hammer for wrist work would also be good additions.
