You just purchased a Lamoureux & Sons knife which requires minimal maintenance to prolong its efficiency and lifespan. The blade is made from high-end CPM-S30V stainless steel, a highly resistance material that maintains its edge.

Regular Maintenance

Blade Maintenance

After each use, clean the blade using a soft moist rag then immediately dry it completely. A small amount of oxydation might be visible and even some rust in case of a lack of proper maintenance. In that case, you can use polishing products offered in good hardware stores.

Handle Maintenance

We mostly use exotic stabilized woods such as Ebony and Cocobolo. Use a soft rag and cool water to clean the handle then another soft dry rag to dry immediately and completely. In case the finish of the handle start to tarnish, you can use citrus oil soap (ex: Murphy’s) then dry by vigorously swiping with a back and forth motion lengthwise along the handle. To finish, use nylon stocking in a back and forth cross-motion perpendicular to the handle.

Care of the Leather Sheath

We recommend using mink oil to maintain the leather supple and permeable. Using a soft brush (horse hair or silk) to remove dirt incrusted in the leather. Make sure the leather is dry then apply a thin layer of mink oil (following manufacturer’s recommendations) and penetrate using a circular motion. Let dry completely. Using a dry rag, apply back and forth motion to thin and solidify the grease. Finally polish using an ultra soft cloth.

To sharpen your knife

Step 1: Prepare the material

We recommend using japanese sharpening wet stones in combination with light vegetal honing oil. The oil’s purpose is to dissipate material deposits, therefore keeping the stone clean, reduce heat and facilitate movements.

The Donxote stone set with grades of 400, 1000, 3000 et 8000 grains per inch are particularly effective.

Step 2: Proper Positioning

Always hold the knife by the handle with the edge facing away from you. Put the blade against the stone with the edge at an angle between 20 to 25 degrees as shown.

Step 3: If the edge lost its sharpness

Start with a rough grain natural stone (between 400 and 600) then finish with a fine grain natural stone (between 800 and 1000).

Use forward motion to push the blade’s edge against the stone then lift at the end of the stroke to prevent touching the blade while returning to starting position to repeat.

For the other side of the blade; use a pulling motion to bring the edge towards you in the same manner, always applying moderate pressure on the blade. Using excessive pressure can damage the stone and leave a material deposit on the edge of the blade. About a dozen passes are necessary on each part of the blade (tip, edge, leading edge) on both sides.

Turn the stone 90 degrees and repeat the entire operation in this orientation. Always keep the stone wet with oil, avoiding too much oil accumulation.

Always push on the blade with a regular and constant motion along the entire length of the surface making sure the blade remains in contact with the stone throughout the motion.

Move on to the next higher grade of stone and repeat the operation to refine more and more your sharpening.

Step 4: If the edge requires a finer sharpening or touch-up

Start right away using a fine grain natural stone (between 1000 and 3000).

Use forward motion to push the blade’s edge against the stone then lift at the end of the stroke to prevent touching the blade while returning to starting position to repeat.

For the other side of the blade; use a pulling motion to bring the edge towards you in the same manner, always applying moderate pressure on the blade. Using excessive pressure can damage the stone and leave a material deposit on the edge of the blade. About 10 passes are necessary on each part of the blade (tip, edge, leading edge) on both sides.

Turn the stone 90 degrees and repeat the entire operation in this orientation. Always keep the stone wet with oil, avoiding too much oil accumulation.

Always push on the blade with a regular and constant motion along the entire length of the surface making sure the blade remains in contact with the stone throughout the motion.

Move on to the next higher grade of stone and repeat the operation to refine more and more your sharpening.

Step 5: Occasional cleaning

If your blade lost its shine, is stained or simply needs a deeper cleaning, you can clean it using stainless steel cleaner and polish with a soft cotton rag. This will remove microscopic deposits that have accumulated on the blade.

Spray the cleaner on the rag, NEVER directly on the blade. Dry using a soft rag using a regular motion along the full length of the blade.
