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.
To blazon arms means to describe them using the formal language of heraldry. This language has its own vocabulary and syntax, or rules governing word order, which becomes essential for comprehension when blazoning a complex coat of arms.
