How to Choose the Best corner cutter tool?

To help you pick the best corner cutter tool for your tasks, examine these very important aspects.

  • Comfortable Grips- The grip design is essential to the operation. You will be exerting a considerable amount of force, so you want to make sure you have something that is both comfortable in your hand and easy to hold onto. While it shouldn’t be a driving reason to consider a corner cutter tool, it is something to prioritize during selection.
  • Foldable Design- If you need to carry corner cutter tool in a tool bag, you might want to invest in a set designed with that in mind. This is especially true if you know you will need longer handles for an increased mechanical advantage. Again, this is not a standard design feature, so you will need to search specifically for sets that offer it.
  • Adjustable Blade- Most corner cutter tool features an adjustable blade. With this adjustment, you can set the proper cutting depth to fine-tune performance. How this adjustment is made can vary, and it is something to pay careful attention to. You want to make sure that the mechanism is both easy to use and will provide reliable results.
  • Cutting Style or Angle- If you think all corner cutter tool cut in exactly the same way, it’s time to take a close look at the ones you’re thinking about buying. corner cutter tools actually have different cut styles, or angles, which creates different end results. You can choose from angled, shear, clipper, or center cut corner cutter tool. Each of these types of cuts can shape how you position yourcorner cutter tool, how much pressure is applied to one point, and how the jaws open.
  • Hydraulic or Hand-Powered- Most corner cutter tool are powered by nothing but your own force applied via the handles. However, you can opt for a hydraulic corner cutter tool if you’d like. In these tools, a motor powers the cutting blades via a hydraulic piston. That piston moves the blades with increased force — more force than you could likely create with hand- and handle-operated corner cutter tool. Hydraulic corner cutter tool is especially helpful if you’re trying to cut through thicker locks.


corner cutter tool are offered in a wide range of sizes: 8, 10, 12, 14, 18, 24, 30, 36, and 42-inches. The cutter size will affect its capacity to cut through a variety of materials and metal thicknesses.

Small corner cutter tool

Small corner cutter tool that size 8, 10-inch, 12-inch, or 14-inches in length are primarily meant to cut through thinner chains and pry off bolts that have a soft to medium hardness. These types of corner cutter tool, such as the outstanding Knipex Tools corner cutter tool, are also quite popular as they are sturdy, fit in tight, confined locations, and enable on-the-go versatility.

Medium Sized corner cutter tool

Medium-sized corner cutter tool range in size from 18-inches-24 -inches. They can be utilized with soft and medium-to-hard metals. As a medium bolt cutter has a long handle, it provides better leverage for cutting through bulky things such as padlocks and removing bolts.

Large corner cutter tool

Large corner cutter tool that measure 30-42-inches are suitable for cutting through medium-hard metal components such as thick steel chains, copper cable, steel rods, and large bolts and padlocks. These heavy-duty tools include super-strong steel jaws and longer handles that provide you with improved leverage and bolt-busting strength for particularly demanding work.


The cutter’s jaws and blade edge must be built of strong, sturdy, and hard steel for maximum cutting power.

Most corner cutter tool are forged from chrome molybdenum or chrome vanadium steel. Both forms of steel are strong and durable. Powder-coated steel prevents rust and corrosion.

Rockwell Scale

Any knife or ax will have a Rockwell Hardness Scale-made blade. The Rockwell Scale’s HRC code indicates steel’s hardness and durability. Higher RHC means tougher steel.


Handles must offer the appropriate leverage to expand the jaws so they may grab and cut metal with less effort.

Ergonomic design reduces hand fatigue. The corner cutter tool may feature thick molded plastic handles, like the Capri Tools CP40209 40209 8-inch Klinge Mini corner cutter tool or rolling steel handles with cushioned non-slip rubber grips.


A heavier corner cutter tool offers more metal-crushing force, but it causes fatigue over time. A lightweight corner cutter tool is perfect for quick chores and everyday transport, but not for heavy-duty tasks. Consider the tasks you must complete. Keep a heavy and a lightweight bolt cutter in your toolbox.
