To remove pitch buildup on blades, mix a 50/50 ratio of chainsaw bar chain oil and diesel fuel in a spray bottle and spray onto blade every minute or so. I have heard stories of using an old car windshield cleaner pump to deliver the solution to the blade. It works very well and I have no pitch remaining on the blade.
Coat of arms. A coat of arms is a unique heraldic design on a shield, escutcheon, surcoat, or tabard. A coat of arms is used to cover, protect, and identify the wearer. Thus the term is often stated as coat-armour, because it was anciently displayed on the front of a coat of cloth in European societies.
Coat of arms: Coat of arms, the principal part of a system of hereditary symbols dating back to early medieval Europe, used primarily to establish identity in battle. Arms evolved to denote family descent, adoption, alliance, property ownership, and, eventually, profession. The origin of the term coat of arms is in the surcoat, the cloth tunic worn over armour to shield it from the sunâs rays. It repeated the bearerâs arms as they appeared on his banner or pennon and on his shield, and it was particularly useful to the heralds as they toured the battlefield identifying the dead.
