What should the handle of the cable splicing knife be like?

One of the most important things of your cable splicing knife is the handle of the knife. The handle is the only part of the knife that will directly be in contact with the user which means that the users will have to pay extra attention to the focus.

One of the finest ways and safest options is to get a rubber type material that will ensure a handy grip. Rubber tends to be non-slippery and hence, even if you exert extra pressure, it will not slip from your hands. However, keep in mind that the rubber should be of great quality otherwise it may just come out when you are using the tool. Plastic is not a good option here as it may not be very durable and it may slip from the hands of the user easily.

Another factor to consider the handle of the knife is to make sure it has a strong grip in some fashion. Some of the handles of a cable splicing knife are made with a pattern so that the grip remains intact; others are made with a finger grooves design to ensure that there is a strong grip. Either one works perfectly as long as the grip is strong.

What aspects of the blade are important in a cable splicing knife?

Short blades are small blades about 1-3/4 inches that ensure that small and even big cables and insulations can easily be cut. However, if the blade is not sharp enough, it may not work on heavier cables which will make it tough for you.

To ensure that the blade is sharp, a cutlery steel blade is the finest option. These blades remain sharp even when they are used a couple of times and they are strong enough to handle the heavy-duty cables without breaking their tips.

What additional features are important?

A few additional features make the cable splicing knives much more useful and right to use, these ones are highly recommended.

Among them, the first is a sheath or a cover. You will need to carry around the knife so it’s better to carry it in a protective layer or a pouch that will help you remain safe from any injuries while you carry it. A pouch usually comes with the knife; however, if your product did not come with a pouch, buy one on the side for protection.

Some of the knives come in a pair with scissors or a gripping/stripping tool. This tool is highly important to strip the wire and to hold it when you are precisely cutting the cable or the insulator.

Some knives simply come in a kit form to help you with all your cable working tools. These ones may be a little overpriced, but if the quality is in check then they are worth it. Kits usually do not focus on small details of the tools which are why they might not be the best option.
