Captains of Crush Hand Gripper Left-Turn – Review

Overview, Details & Everything Relevant You Need To Know

What is Captains of Crush Left-Turn?


CoC Left-Turn is a new innovation – Essentially a mirror image of Captains of Crush gripper to train your left hand.

It’s about spring positioning: If you use right hand gripper in your left hand, you’ll notice the twist of the axis of the gripper changes. Some folks find it feels different & perhaps even harder to close a gripper device.

To make things even for your left hand & train it the same way you’re training your right hand, IronMind decided to build an entirely new gripper that looks like & technically is the Captains of Crush gripper, with one difference: It uses left-wing spring, making it a perfect fit to train left hand. Left-Turn is a mirror image of Captains of Crush.

Whether you’re weight lifter, rock climber, wrestler, motocross driver, strong grip is a must to be on top of your game.

Like your regular Captains of Crush, CoC Left-Turn has high quality. It’s made of aircraft grade billet aluminum & alloy steel construction giving it superior performance. Made by IronMind, an industry leader since 1988.

Manufacturer also offers a 1-year warranty to their world famous spring grippers, in case you manage to break one.

What are the Pros & Cons with Captains of Crush?

Knurled Lefty Gripper


  • Lefty Gripper – One of the few grippers available that uses left-wing spring which is specifically designed to train your left hand the same way you would train your right hand.
  • High Quality Product – A professional grip training device, that is designed for low-volume, high-intensity training. Hand crafted device with aircraft grade aluminium & alloy steel.
  • Superior Performance – A grip device that is built in a way to boost your forearm strength for maximum amount possible in shortest window of time.
  • 4 Different Resistances – You can find suitable match for your regular Captains of Crush gripper to mimic the same training sensation in both hands. There are resistance levels from beginners to experts (100-280 lbs).
  • Very Durable – Like all CoC gripper, this one is completely made of metal parts to give it maximum durability – You’ll find no plastic parts that can degrade, chemically deteriorate or break over the time.
  • Aggressive Knurled Handles – One of the biggest part to get your grip stronger is also getting the skin of your palms tougher. CoC gripper knurling tears up the palms of your hands to help them to get much stronger overall.
  • Portable – Simply put one into your pocket or leave into your office desk drawer. You can throw one into your training bags as well once you hit the gym. It’s a small device, so you can always have one near & never miss your grip workout.
  • Easily Maintainable – Like most things made from metal, this gripper will oxidize in humid climates. To avoid rusting you should wipe spring occasionally with a drop of light oil to make it move smoothly, prevent it from squeaking & breaking. Also, knurled handles can be cleaned with a stiff nylon bristled brushes.
  • 1-Year Warranty – Your grippers will be replaced free of charge if they fail during proper use within one year of the date of purchase. To claim replacement, both gripper & proof of purchase must be returned. Improperly used, modified or damaged grippers are not warranted.


  • Designed for One Hand – This model is designed to train your left hand first & foremost. Meanwhile, it’s still excellent for training both hands, with slightly different feeling when training your right hand. In most cases, it’s a minor detail that most folks won’t notice at all – If you seek maximum comfort, performance & precision, for right hand training I’d recommend to use regular Captains of Crush line grippers to complement your CoC lefty gripper.
  • One Resistance Level Per Gripper – Compared to adjustable hand grippers, CoC is a static one-difficulty-only per gripper type of training tool. If you’re serious about getting stronger & to get maximum out of your training progression & to have more variety it likely requires more investment from your side to access grippers with different resistance levels.

Gripper training is excellent for both, beginners & experts alike to get your grip stronger, or even stronger than it already is.

Younger or older, man or woman, casual trainee or hardcore athlete, training grip is giving you functional strength that you can use & likely will use every single day. In most sports, the very first point of contact with object is literally through your fingertips. Doesn’t matter if you’re holding a basketball, baseball bat, golf club or weightlifting barbell..

The more functional strength you have in your hands, the better the performance in your respective sport likely will be.

Exercise with hand grippers and avoid using fitness gloves

Toughen Your Palms With Hand Grippers

Avoid Fitness Gloves

Why should you always avoid excessive use of fitness gloves? Many folks rely entirely on gloves when they hit the gym & as a result they usually have extra weak palms. Gloves are a “foreign” objects (between your palms & a weight you’re lifting) that directly prevent your palms getting stronger.

If that’s the case, once you take off your fitness gloves & touch the first barbell or dumbbells you see, you’re going to shred the palms of your hands almost instantly. Your hands definitely start aching & in the long run you likely get blisters.

So, how do you solve that problem? No, you don’t put your gloves back on – Captains of Crush has aggressively knurled handles that is specifically designed to toughen the palms of your hands. Keep training, your hands get stronger, simple. Gradually, over the period of weeks & months, while regularly exercising with grippers, skin in your palms will toughen up. It’s one of the key parts to be able to perform more strenuous exercises with bare hands.

Unless your hands are injured, OR you’ve already worked your hands to limit, you have no excuse OR likely no practical reason to use fitness gloves – You always want to put fitness gloves away & work with bare hands for functional strength.

As always, for rehab purposes & for hand health in general, having balance is key for getting much stronger in functional strength department. I recommend to pair up your gripper training with extensor training – For that task you can use rubber hand bands to work on counter-movements to balance your hand muscles.

They’re inexpensive & they keep your hands pain-free.

Your Grippers Quality is Paramount

Why Should You Always Choose a High-Quality Gripper?

Consistency & Precision

It can happen, that after couple of weeks of using a cheap plastic gripper you’re going to close it like a champion. It likely gives you a feeling that you’ve progressed so much already in such a short time. Have you?

If you’re a realist you know it’s clear as day that nothing is invulnerable – If you try hard enough, you can break CoC grips as well – That usually happens only when you maintain your equipment poorly: For example, storing grips in too humid conditions, not keeping equipment clean or on top of it, modifying or exercising improperly with your gripper.

1The reality is that cheap grippers spring will wear out quickly. It keeps getting weaker & weaker.

Meanwhile you’re getting stronger, cheap gripper spring is getting weaker. In short: They’re likely inconsistent. Inconsistency often includes their geometry. Uneven handles, spring positioning. Small but effective nuances.

2Another problem is that cheap gripper springs tend to snap easily. That’s a safety issue for you.

There’s a chance that you’ll injure yourself, especially when spring snaps in the middle of the exercise & you’ll get hit by the shards of broken spring.

It’s better to invest into high quality hand gripper – They are consistent across the board & there is much less chance for equipment failure. In addition being well engineered, there is no surprise geometry, so you can monitor your results more precisely. You’ll get quality, train like a professional & eliminate guess-work from your workout routines.

2 thoughts on “Innovative Captains Of Crush Hand Gripper Made For Lefty?

  1. Your review of the COC Left Turn gripper for left-handed users is incredibly informative. It’s refreshing to see a product cater specifically to lefties. I’m curious, how does it compare in terms of durability and resistance levels to the standard COC grippers? Additionally, have you noticed any specific improvements in your grip strength since using it? Personally, I’ve struggled with finding suitable grip trainers, so this detailed review is greatly appreciated.

    The breakdown of the design and usability is spot on. Your mention of the ergonomic handle design is particularly intriguing. I’ve often found discomfort in extended training sessions, so this feature sounds promising. How has this gripper influenced your training routine, and have you noticed any reduction in strain or discomfort? Your insights could be immensely beneficial for others considering this product. Thank you for providing such a thorough and helpful review!

    1. It’s the very same thing, just mirror image of regular Captains of Crush. To break one you either have to low roll a faulty device from manufacturer or mishandle your device to greater extent to break it. Durability isn’t issue here, these things are built like tanks. Been repping my CoC grips for years, still feels like I bought them yesterday.

      To be frank it’s a flavor item for those who are gripper gurus, just nit-picking, or progressed above normal & seeking to get all the angles perfect. Most people won’t even pay attention to detail as such. Right or left winged spring, tells them absolutely nothing.

      Fortunately there’s a compromise, a middle path so to speak with gd grip ext that does not have bent axis. It’s completely straight & feels the same in both hands. I’ve also reviewed one of those in gripper section, in my opinion it has a level of craftsmanship overshadowing even this famous line of grippers.
