Uses of Utility Knives

If you were asked to list the most versatile tools, you probably wouldn't even think to mention a utility knife. After all, is it just a sharp knife handle? But the beauty of the utility knife is its simplicity. Like many great tools, they are not designed for one specific purpose, but are absolutely necessary for many tasks. If you use a tool to cut wires and only use it to open packages, you're missing out.probuilt, a manufacturer of wholesale utility knives, has summarized for you some of the uses of utility knives.

Slicing the veneer before cutting

Cutting hard plywood can be difficult. If you use a circular saw, you can see the edges of the plywood cracks. Fortunately, there is a way to use a hobby knife as a guide to create sharper lines.

First, take a knife and make a light-colored line along the outer edge of the cut line. Simply press lightly to cut the top layer of the veneer. When you use a circular saw to cut the veneer, this will give you a clean break in the scored line. No splinters!

Consider safety first, especially if you are performing a task that could result in hand injury. In this particular case, the safer the blade, the better.

Trimming wood shims

If you intend to level an installed door or window, shims are essential. It may not be perfectly straight, but it's a good idea to adjust the wood shims slightly. You will notice that when they are in place, the shims protrude from the side of the door frame. This is where a utility knife is needed.

You can use a utility knife to remove the extra shims to ensure they are properly installed in the door frame. Use the blade to score the shims on the door frame. Then bend the wires and expel the excess. Make sure you have a good grip on the knife so your hand doesn't slip.

Remove old caulk

Whether you do winter weatherproofing every winter or replace caulk around a sink or shower, you should cut out the old caulk before applying new caulk to a joint or seam. This can be done by cutting along the edge of the existing caulk with a utility knife, which will loosen it up and make the rest easier. If you pry out even just a corner of the loose caulk, you can usually grab it with your fingers and pull the rest of the caulk into a long strip.

Cutting cable insulation

There are wire strippers specifically designed to remove the hard sheath of non-metallic (Romex) cables, but I've never seen an electrician use them. Most people use a utility knife to strip the outer sheath.

Tip: Take one end of the cable and straighten and flatten it 8 to 10 inches. Place it on a hard surface and use a utility knife to cut through the outer sheath. Be careful not to cut into the insulated wire inside the cable. Grasp the sheath with lineman's pliers and peel it away from the insulated wire. Now use the cutting pliers on the pliers to cut the peeled sheath off the cable.

Cutting Fiberglass Insulation

A sharp utility knife easily cuts through fiberglass insulation and its kraft paper or aluminum foil waterproofing.

Tip: You may find that the blade is too short to completely cut through thick fiberglass. You can cut flattened fiberglass sheets by placing a board on top of them and then kneeling down to press the fiberglass.
