Irwin Vise-Grip Multi-Tool vs Leatherman Crunch: The Heavy-Duty Locking Plier Multi-Tool Debate

Introduction

Some multi-tools chase elegance with slim handles and a dozen delicate implements. Others chase brute utility. The Irwin Vise-Grip Multi-Tool belongs firmly to the second camp, and after spending real time with it, it is easy to see why it keeps earning a spot in working toolboxes.

This is not a new idea. It is a well-proven locking plier design that has been around for a long time, with two genuinely useful additions bolted onto the concept. But the result is a tool that, in some ways, outperforms anything the major multi-tool manufacturers currently offer. Here is how it stacks up against its closest rival, the Leatherman Crunch, and who each tool actually suits.

The Irwin Vise-Grip Multi-Tool: Built Like a Tank

The 5-inch variant reviewed here combines classic Vise-Grip locking pliers with two additions: a one-hand-openable, partially serrated blade held by a liner lock, and a steel bit holder inside the frame using a ball detent design with flat head and Phillips bits included.

The headline feature is strength. The frame is forged steel, and nothing from Leatherman, Victorinox, SOG, or any other major manufacturer makes a multi-tool built quite like this. You could reasonably stand on it without concern, because the structure is simply not comparable to the stamped and machined frames of conventional folding multi-tools.

It is a heavy-duty utility tool first, a pocketknife second. The blade will not win any awards for refinement, but it cuts boxes, strapping, and whatever daily tasks come up, which is exactly what most people actually need from a multi-tool blade.

The Built-In Bit Holder Changes the Math

The ball detent bit holder inside the frame opens up far more than the two included bits. Pair it with an inexpensive bit holder extension and you get access to standard quarter-inch bits as well as ball detent bits, effectively turning the tool into a proper high-torque screwdriver.

That matters because the plastic-handled bit kits most people own flex and creak under real torque. This forged frame does not. Combined with a comprehensive driver kit such as the Klein 27-in-1 tamper-proof set, the result is a genuinely capable heavy-duty screwdriving setup that still folds down to pocket size.

One honest drawback: the bit holder itself does not lock. It is a minor annoyance, but worth knowing before you buy.

The Saw Blade Mod: A Hidden Superpower

With a small Dremel modification, a groove cut into both sides of the jaws in about three minutes, this tool gains an ability no stock multi-tool in this class offers: it can lock in any T-shank saw blade. Even a reciprocating saw blade locks in securely, with the jaw teeth grabbing the blade so firmly it cannot be twisted out in either direction.

The result is a one-handed handsaw with a large, rock-solid handle. It would likely work just as well with a file, and a diamond file from something like a Leatherman Surge would fit without issue. In that context, this setup is arguably more stable and secure than the T-shank holder on the Surge itself.

The modified groove does not affect the plier function at all, and it even adds a secondary use for starting holes for screws. It opens up a genuine bushcraft angle too: carry a pruning blade and you have a compact woods tool with serious cutting, gripping, and wire-cutting capability. This kind of plier is strong enough that cutting heavy fencing wire is plausible.

The Leatherman Crunch: The Polished Original

The Leatherman Crunch is the closest thing to this design philosophy from a major manufacturer, and it is back in production. It remains the more refined choice, with better finishing, tighter tolerances, and the classic Leatherman folding plier experience.

The trade-off is price and strength. The Crunch costs significantly more, and its construction simply is not forged the way the Irwin is. For sheer abuse tolerance, the Irwin will take punishment the Crunch would not shrug off. If the Crunch feels out of budget, the Irwin is the next best thing, and in some ways the stronger tool. But if you value refinement and a more versatile folding design, the Crunch remains the premium pick.

The Long Nose Variant

A second variant with long nose jaws is also available. It does not suit the saw blade modification as well, but the extended jaws make it more useful for reaching into tight spaces, and some users will find it genuinely more practical for electrical or mechanical work.

One caution: the sample unit arrived with slightly loose joint heads, apparently under-peened at the factory. It still functions fine, and at the price it did not feel worth returning, but check the pivots on arrival.

Things to Consider Before Buying

These tools sell for well under $20, with pairs of variants found combined for around $26 on the used market, and individual units around the $12 to $13 mark. At that price, the value is hard to argue with, and quality control hiccups are forgivable.

What you are giving up compared to a Leatherman Crunch or a traditional folding multi-tool is polish and packability. The Irwin is bulky, the blade is ordinary, and the bit holder does not lock. But if you want something multifunctional and genuinely heavy-duty, especially if you are not a multi-tool person in general, this may be exactly the tool for you. Even with more money to spend, many buyers would still choose it for the forged strength alone.

Conclusion

The Irwin Vise-Grip Multi-Tool is not trying to be elegant, and that is the point. It is forged, cheap, nearly indestructible, and with a small modification it becomes one of the most capable compact saw platforms available. The Leatherman Crunch remains the refined, premium option for those who want polish alongside the locking plier format. Pick the Irwin for raw strength and value; pick the Crunch for refinement. Either way, the locking plier multi-tool earns its place in the kit.
