    摘要： A carbide-tipped circular saw blade is formed by brazing cutting tips of tungsten carbide to the teeth of a steel blade blank, thereby creating discoloration on the planar surfaces of the blade adjacent the rim. Substantially the entire surface of the blade is sandblasted with blast media to remove the discoloration while generating a substantially uniform coloration and texture to the planar surfaces of the blade. User-readable graphics are overprinted upon the blasted surface. The graphics and the surface appearance of the blasted area are selected to be at a predetermined contrast, and the carbide cutting tips retain a visual appearance different from the rest of the blade, such that the graphics and cutting tips are visually perceptible to a potential purchaser at the blade's point of sale. The saw blade surfaces are sandblasted by jets directed at both sides of the saw blade. The blast nozzles are oriented such that the vertical components of force of the jets offset one another. This assists in minimizing the blade warping that would otherwise occur due to the sandblasting operation. In all-sandblasted "softbody" blades, a reduction of 20% in deviation from flatness has been achieved compared to similar blades which are polished and rim-blasted.

    摘要翻译： 通过将碳化钨的切割刀片钎焊到钢刀片坯料的齿上形成硬质合金刀片圆锯片，从而在邻近轮缘的刀片的平面表面上产生变色。 基本上，叶片的整个表面用喷砂介质喷砂以除去变色，同时对叶片的平面表面产生基本均匀的着色和纹理。 用户可读的图形在喷砂表面上套印。 爆破区域的图形和表面外观被选择为预定的对比度，并且硬质合金切削刀片保持与刀片的其余部分不同的视觉外观，使得图形和切割尖端在潜在购买者的视觉上可察觉 在刀片的销售点。 锯片表面被喷洒在锯片两侧的喷嘴喷砂。 喷射喷嘴被定向成使得喷嘴的力的垂直分量彼此抵消。 这有助于最小化由于喷砂操作而否则会发生的叶片翘曲。 在所有喷砂“软体”刀片中，与抛光和边缘喷砂的类似刀片相比，已经实现了与平整度的偏差减少了20％。

    摘要： A saw blade is stamped with a circumferential edge. At least one gullet and shoulder are formed in the circumferential edge. Likewise, a tooth pocket is formed in the circumferential edge. The tooth pocket is defined by a wall, generally radial to circle, on the shoulder, and a shelf substantially perpendicular to the wall. A tooth is secured, ordinarily by brazing, in the pocket such that a portion of the shelf extends beyond the front face of the tooth towards the gullet so that the tooth can be brazed along its entire lateral edge such that resultant forces in the tooth are transmitted to the body of the blade. After the tooth is positioned into the tooth pocket, the tooth, as well as a projection of the blade shoulder, are ground off so that the tooth and shoulder are flush with one another. Thus, the tooth longitudinal edge is in complete contact with the shoulder wall maximizing its strength.

    摘要： An improved portable work bench includes a beam, legs for supporting the beam, a bracket for supporting at least one of an accessory and a power tool, and a handle assembly connected to the beam. The handle assembly is movable between a retracted position near the beam and an extended position away from the beam.
