Bolster brass 40х21х5mm, with hole 12x1.5mm

Bolsters are a design element of a knife, which is designed to distribute bending mechanical loads that occur at the junction of the knife handle and blade.

For the manufacture of bolsters, as a rule, hard and durable materials are used, such as: metals (copper alloys / brass, bronze, cupronickel /, stainless steel, titanium, aluminum alloys, etc.), non-prickly and hard woods, horns / bones /animal teeth, as well as various hard plastics (polyester, acrylic, bakelite, etc.). The most commonly used material for bolsters is brass, as the material is relatively cheap, easy to work with, effectively fits into the design of any knife and always complements any handle inlay.

The presented blanks for bolsters are made of LS-59 brass (the so-called loose brass), which is very easily subjected to any machining (sawed, ground, polished), while it is wear-resistant and easy to clean. The composition of brass brand LS-59 includes up to 60% copper, about 40% zinc and up to 2% lead. It is the presence of lead in the composition of the alloy that reduces ductility (compared to two-component alloys) and makes it possible to effectively process it by cutting to obtain small chips. The workpiece is an ellipse, along the contour of which you can easily fit the adjacent handle. Since the material of the handle is usually much softer than brass, when fitting with sanding, it is recommended to apply it (grinding) to a solid base in order to avoid parasitic sampling on the handle at the junction with the bolter.
