    • A scraper blade preferably configured for use with a reciprocating saw. The blade has a first end comprising a mounting structure, and a second end with a cutting edge. The second end is coupled with and spaced apart from the first end. Preferably, the first end is configured to be mounted in a reciprocating saw chuck and the first and second ends are integral. Further, the first and second ends are preferably manufactured from heat treated steel comprising between approximately 0.45 to 1.05% carbon and between approximately 0.3 to 1.0% manganese. Preferably, the steel has a yield tensile strength of between approximately 150,000 to 250,000 pounds per square inch, a modulus of elasticity of between approximately 20,000 to 40,000 kilopounds per square inch, and a hardness on the Rockwell C scale of between approximately 30 to 60.
    • 优选地构造成与往复锯一起使用的刮刀。 刀片具有包括安装结构的第一端和具有切削刃的第二端。 第二端与第一端连接并间隔开。 优选地,第一端构造成安装在往复式锯夹头中,并且第一和第二端是一体的。 此外,第一端和第二端优选由包含约0.45至1.05%的碳和约0.3至1.0%的锰之间的热处理钢制成。 优选地,钢的屈服拉伸强度在约150,000至250,000磅/平方英寸之间,弹性模量在约20,000至40,000千磅/平方英寸之间,以及洛氏C尺度上的硬度在约30至60之间。
