也许我没说清楚,我砍的就是山核桃树,也就是山胡桃,木料内心是红色的。
请问一下为什么斧头柄不用里面的呢?
我挑Gransfors 斧头的时候,专门给商家说要颜色深的。
我手上有几只Gransfors 的斧头,浅色的用刀 ...

我前面的发言有误,编辑了一下,请注意。
关于斧子柄的选择, 参考:http://www.fhwa.dot.gov/environm ... 23/page10.cfm#basic
Basics of Handle Selection
Hickory makes the best handles for percussion tools like axes. You seldom see any species other than hickory offered by ax-handle companies.
There are several important characteristics you need to look for in a good ax handle. Generally, you get what you pay for, because the higher grade hickory handles sell at a premium over lower grade handles. Your new handle should be of straight grain, second growth, clear hickory. Cheap, inferior handles tend to break, split, and warp. If you are going through all the work of hanging your own ax, you should spend the extra dollars to get a high-quality handle. Some characteristics you need to look at include:
Color: The best handles are from second growth hickory sapwood, all white in color . In lower grades, various amounts of red-colored heartwood are in the handle.

white sapwood makes the best ax handles.
This particular piece is too small and too
riddled with checks to be good handle stock.
芯材和边材之所以有颜色上的差异,跟它们的结构功能和成分这几方面的区别有关,与fatwood形成的原理无关,所以深色部分并不是fatwood。
照理说芯材比边材更硬更结实,更适合加工成工具,但是斧柄除了要坚以外,更需要韧。 |
