Hickory has well above average properties for durability, strength and shock resistance and is very common (in e North America), grows big and straight and is easy to process. Handles made of American hickory set the standard for the entire worldwide implement industry (including hammers, sledges, axes etc in Britain, Scandinavia and Europe) already 125 years ago. Eastern Canada gravitated towards Ash only because there usually is a huge one of these trees at every street corner, bush lot, forest edge and hedgerow but striking-tool-maker purists like Morley Walters insisted on importing hickory for his Canadian axes despite the ease of getting hold of local ash lumber. Notice though that the entire hockey stick industry up until 40 years ago was dominated by Ash, so the stuff can't be all that bad!
