The utility knife is a knife with a blade adjustable by the user. In this kind of knife, the user can control and adjust how long the blade would extend. Because of its unique design, it has become the first choice for people who want to cut materials made of paper, wood, plastic, and other such materials.
Although many people think that the utility knife is a very useful tool, there are still some who are uncertain on what kinds to buy or how to choose the good ones. If you are having difficulties in choosing a good utility knife, here are some points to look for that might help you.
Blade. The blade is the most important part of the knife. Having it blunt makes the knife useless. A good blade should not have broken or cracked sharp edges. These broken edges make cutting difficult, and might cause bumps or jumps while doing the cutting motion. A good blade should also be free of rust. Blades are often exposed to moisture and air which may cause rusting. Rust makes the blade blunt and may also cause tetanus in the event that skin is cut. It is better to choose blades which are stainless. However, if you want to use safety blades, there are also utility knives with plastic blades. These blades are advisable for use of minors.
Handle. The handle takes part in giving support and control over the knife. A good handle should be comfortable for the hand of the user. It should not cause too much pressure or stress on the hand. There are some utility knives which are specially designed to fit every finger of the hand. This design helps a lot so that the knife would not slip the hand if ever it becomes too sweaty. Utility knives with rubber handles also give a good grip.
Lock. The user should be very certain that the lock for the blade is functioning properly. The lock should hold the blade firmly. Loose locks may cause the blade to retract when great pressure is exerted while cutting. Loose locks may also cause injury if ever the blade comes out unexpectedly. Make sure that the utility knife that you will purchase has a tight lock.
Length. The length of the utility knife and its blade matters a lot. The blade determines the thickness of the material that the blade would be able to cut. Thin materials like paper, plastic sheets and cloth do not need a very lengthy blade for the end of the blade is the only part that will be used. Thick material like wood, wax, and the like, need longer blades, so that more of the sharp surface would touch the material. The sharper the surface that touches the material makes the sliding motion of the cutting easier.
Choosing a good utility knife takes some time, but this ensures that you purchase a good quality knife. When shopping for tools like knives and blades, consider that safety should be a priority.
