      Safety glasses and goggles are made from numerous types of lens material, and it helps to understand the differences between them.

      Polycarbonate offers excellent impact and scratch resistance, is lightweight, and can offer some protection against ultraviolet rays. The downside to polycarbonate would be that its optical clarity isn’t as great as NXT polyurethane or optical glass.

      NXT polyurethane (Trivex) also offers excellent impact resistance, has premium optical clarity, and is lightweight. Its downside would be the higher price tag, but some would argue that having better optical clarity is worth the investment because being able to see well could help to prevent other injuries in the shop.

      Acrylic lenses are often the most inexpensive. They are not very durable, nor do they have very good optical clarity, but they are resistant to solvents.

      Optical lenses are choice for those who prefer prescription glasses. They often have excellent scratch resistance and offer distortion-free vision. The downside would be that they are heavier and come with a higher price tag. Generally, they additionally have poor impact resistance.

      HEARING PROTECTION

      At any given time the knife shop can put off a good amount of noise. Any sounds louder than 85 decibels have the potential to cause hearing loss. Whether you’re using a belt grinder, forging with a hammer, or cutting handle material with a band saw, it’s important to keep those ears covered.

      Earmuffs are my preference.

      Earmuffs cover the entire ear and often have the capability of being attached to a helmet or face shield. They are available in many different styles and have been a preference of mine for quite some time.

      Earplugs are available in a multitude of styles, such as foam plugs, silicon plugs, or universal plugs.

      Foam plugs are often yellow in color and designed for one-time use. Foam plugs come with a cheaper price tag, they can irritate the ear, and when inserted using a dirty finger they pose a risk of external ear infections.

      Silicon plugs are also one-time use but are made from a less irritating material. These are designed to only cover the auditory canal, and they cannot be inserted into the ear, which in turn makes it easier for them to fall out.

      Universal plugs are the popular choice. These offer a layered system and completely seal off the auditory canal. Their design helps protect against sound while preventing the sense of being completely shut off.

      The shop can be a dusty place. Protect your lungs with a respirator.

      LUNG PROTECTION

      Whether you’re sculpting a handle, cutting steel, or grinding bevels—anytime there is dust present—a respirator is necessary. Respirators are among the most important pieces of personal protective equipment you can use.

      The best footwear for the shop is a pair of all-leather boots that rise above the ankles.

      Particulate respirators are what should be used in the knife shop. They are designed to capture particles in the air. The filters should be approved for at least 95 percent filtration efficiency. They do not protect against gases or vapors.

      Leather apron, leather gloves, and a welder jacket are great to have in the shop.

      PROTECTIVE CLOTHING

      In the knife shop, you could be working around hot steel, hot oil, hot tools, sparks, and flames, so it is extremely important to wear clothes that are appropriate for the job. This means no synthetics СКАЧАТЬ
