To help, prop up, strengthen or reinforce. A knife bolster is a thick junction between the handle and the knife blade which provides a smooth transition from the blade to the handle. It strengthens the knife, adds durability, and provides a counter-balance. Since the handle is lighter than the blade, the bolster contributes to better balance and improves control.

Vaccinia virus is a member of the orthopox virus family, which includes smallpox (variola), cowpox, monkeypox, gerbilpox, camelpox and others.When inoculated in the superficial layers of the skin, the virus grows and induces an immune reaction that serves to protect against smallpox.A successful vaccination is often referred to as a take.
