How to Use Oil Stones for Knives, Tools, and More

In the world of abattoirs and slaughterhouses, maintaining sharp tools is a matter of productivity and safety. Oil stones are a traditional and effective method for keeping knives and handsaw blades in top condition. Here’s how to use them effectively.

Understanding Oil Stone Uses

Oil stones are used to sharpen and hone the edges of cutting tools. They are typically made from Novaculite, Aluminum Oxide, or Silicon Carbide and come in various grits for different sharpening stages.

Step-by-Step Guide to Using Oil Stones

• Select the Correct Grit: Start with a coarser grit to remove any nicks or dullness, then move to a finer grit for honing.

• Apply Oil: Lubricate the stone with oil to reduce friction and prevent metal filings from clogging the stone’s surface.

• Sharpen the Blade: Hold the knife at the correct angle and push it across the stone with even pressure. Repeat on both sides until sharp.

• Clean and Store: After use, clean the stone with a little detergent and a brush, let it dry, and store it properly to ensure longevity.

Safety First with Chain and Steel Gloves

When sharpening tools, it’s crucial to wear protective gloves. Chain gloves and steel gloves provide a barrier against accidental cuts, allowing for the safe handling of sharp blades. 

These gloves are indispensable for worker safety in the demanding meat processing environment.

Maintaining Handsaw Blades

Regular maintenance of handsaw blades includes cleaning, lubricating, and sharpening. A well-maintained blade ensures clean cuts and extends the life of the saw. Remember to lubricate the blade after sharpening to protect it from rust and corrosion.

The Meat Processing Industry Adopts Oil Stones

The widespread adoption of oil stones for sharpening in UK abattoirs and slaughterhouses can be traced back to the Industrial Revolution when the mechanisation of many processes included the need for more efficient tool maintenance.

During the 19th century, oil stones became a staple in these settings, providing a reliable method for keeping blades sharp.

The impact on the industry was significant. Sharper knives meant cleaner cuts, less worker effort, and reduced time taken to process meat. This efficiency gain contributed to the scaling up of operations, allowing for the faster processing of animals and better quality cuts. 

The adoption of oil stones marked a shift towards more professional and standardised meat processing practices, setting the stage for today’s modern industry. 

The use of oil stones has continued to evolve, with new materials and technologies enhancing their effectiveness and ensuring their place as an essential tool in the meat processing chain.

Does an Oil Stone Have an Advantage over Other Sharpening Tools? 

Oil stones do have certain advantages over other sharpening tools. They are known for their solid overall performance and are particularly beginner-friendly. 

Oil stones are also less expensive and more durable than many other types, making them a cost-effective and long-term investment. 

Additionally, they are less likely to wear down over time, so they don’t need to be replaced as often as some other types of stones. However, it’s worth noting that oil stones tend to sharpen more slowly compared to water and diamond stones. 

This slower speed can be a drawback for those who need to sharpen tools quickly, but it also allows for more control during the sharpening process, which can be beneficial for beginners or those who prefer a more measured approach.

Novaculite – A Form of Quartz is the KEY

An oil stone typically comprises a fine-grained sedimentary rock known as novaculite. Novaculite is a form of quartz prized for its abrasive qualities, making it ideal for sharpening and honing blades. 

The stone’s structure is dense and even, allowing for a smooth sharpening process. Oil is used as a lubricant on these stones to carry away the metal filings (swarf) produced during the sharpening process, which helps to prevent the stone’s pores from clogging and maintains its effectiveness. 

This combination of novaculite and oil provides a reliable and traditional method for achieving a sharp edge on various tools and blades.

Quality Blades = Less Sharpening 

Depending on the quality of the knives you use and the level of the chain you are in will determine your need for the best knife sharpener. 

For example, you won’t need to worry about sharpening often if you are using Giesser knives or Victorinox knives due to the high-grade metal composite they use with their blades across multiple disciplines. 

For lower-grade tools, adherence to sharpening is necessary and something you need to schedule into your work.

SUMMARY

Oil stones are a reliable resource for keeping your cutting tools razor-sharp. Paired with the right safety equipment like chains and steel gloves, they form an essential part of the toolkit in any meat processing facility. By following these steps, you can ensure that your tools are always ready for the task at hand.
