Bernal Cutlery Borachrome™ Precharged Deburring Strop

Rubberized cork strop charged with Borachrome compound for deburring knives finished under 2000 grit, ideal for toothy medium grit finishes; 600 to 1k grit finishes are its ideal zone, great for Western knives

Excellent for de-burring western stainless steel with a 1000 grit finish or for more stubborn alloys that are difficult to de-burr with a finer finishing chromium oxide. The addition of boron carbide gives this de-burring compound extra cutting power without losing the de-burring ability of chromium oxide.

13" x 3" x 5/16” - 33x75x8mm

Borachrome de-burring and polishing compound is made with a proprietary mix of chromium oxide and boron carbide at roughly 15,000 to 4000 grit in a water based paste with the majority of the product being abrasives. The boron carbide in Borachrome has a much more aggressive cutting ability than chromium oxide on its own, yet still creates fine finish edges with the presence of chromium oxide.

This cork strop is our shop favorite for de-burring in tandem with a paste compound. It successfully de-burrs and enhances the finished polish; finely honing the work of the fine synthetic or natural stones. It is a very dense composite, approximately 15 to 20x more dense than a regular cork pushpin board. 

Since this strop is made from rubberized cork, it can be cleaned with soap and water to remove compound or other kitchen debris. Lifespan of charge will vary depending on volume and intensity of work. New compound should be reapplied once the bare cork reemerges on the majority of the strop.

When used with paste compounds, let the compound fully dry before stropping. A small amount should be spread thinly over the strop and cover most of the strop face; re-apply a smaller amount over spent abrasive, a little goes a long way!
