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.
