How Do You Use a Nut Splitter?
Using a nut splitter is quite an easy task that anyone can perform. Here are steps to observe when using a splitter to crack a nut:
- Step 1: Unscrew the Chisel: Turn the head of the screw in an anti-clockwise direction pushing the chisel into the splitter handle until the nut can fit between the anvils and chisel.
- Step 2: Position the Chisel: Place the nut splitter’s frame over the nut, line the chisel, and avail with the flat sides of the nut. Ensure that the chisel is well situated in the center of the flat side of the nut.
- Step 3: Tighten the Chisel: Tighten the chisel by turning the head of the screw in a clockwise direction. Pinch the stuck nut in between the avail and chisel of the nut splitter. Go on tightening the screw with a spanner, socket, or wrench to deliver enough torque. When you hear a crack sound, it means that the nut is split, and you should stop. You may be needed to hold the nut splitter in place throughout the process.
- Step 4: Unscrew the Chisel: Unscrew the chisel by turning the nut splitter’s head in an anti-clockwise direction. The chisel will disattach from the nut and move back into the handle.
- Step 5: Repeat the Same on the Other Side: Nut splitters have one chisel, and thus you need to repeat the process to crack the other side of the nut. The nut will split into two without damaging the bolt thread.

Among the first things to consider when buying a nut splitter is its size. A nut splitter helps you to crack and remove stubborn and stuck nuts, but it will not work if it is not of the right size. The sizes range from one splitter to another. Some handle small nuts while others deal with larger nuts.
Check the size of the nut you want to remove before the purchase. The size of the nut will guide you on the correct size of the nut splitter. You can also choose to buy an adjustable nut splitter, which will help you deal with all nuts irrespective of their sizes. Some companies also sell several splitters of different sizes in one set.
A nut splitter may seem like a simple tool, but you need to make sure that it will serve you for a long. You may not be able to distinguish a good nutcracker by just looking at it. The best way to get a high-quality nut splitter is to buy from a well-known brand. Above, we have stated some of the best nut splitters you can consider buying. Read the reviews of previous buyers and see what they have to say about the tool.
Generally, nut splitters have the same design, and this confuses buyers on the better one to buy. The difference in construction depends on what materials have been used to make the splitter and the process it has gone through. A good and reliable nut splitter should have a sturdy construction that will not break after using it just a few times. Some of the best nutcrackers are constructed with heat-treated hardened and forged steel. Always choose a cracker that feels sturdy and heavy.
The design of a nut splitter will determine if it will be able to get in hard-to-reach areas or not. Sometimes you will need to remove stuck nuts in tight areas, and you need a splitter that will easily get there. Consider the size and the design of the nut splitter before purchasing it. Small crackers seem to get in tight areas easily. However, some are made with a reversible design enabling them to get your desired cutting angle.
When buying any tool, we are always on a budget. Nut splitters are of different costs, which could be an indicator of their quality. However, there are also low-priced nutcrackers but still high quality. Do your research well and get the best nut splitter you can within your budget.
