打平锤的工具评测与锤柄自制

挑选 400 g 级打平锤先看锤面硬度：HRC 50–55 最合适——低于 HRC 45 会快速墩成蘑菇头，高于 HRC 60 则在铜面压出过深印痕；球面曲率按工件分 R80–150 mm 两三档备用。自制锤柄选含水率 8% 以下的白蜡木或山胡桃木，柄孔装入后以木楔胀紧，柄长按身高取 320–360 mm，装好试挥 200 次检查楔口无松动。评测中还发现一体钢柄锤减振最好但冬季握感冰冷，麻面喷塑柄防滑性最佳，属使用场景取舍。
When reviewing a 400 g planishing hammer, start at the face: HRC 50–55 is ideal—softer than HRC 45 mushrooms quickly, harder than HRC 60 prints too deep into copper; keep two or three curvatures on hand, R80–150 mm. For a self-made handle use ash or hickory below 8% moisture content, wedge it into the eye, length 320–360 mm to suit your height, then test-swing 200 strokes to confirm the wedge holds. Reviews consistently find one-piece steel handles damp best but feel cold in winter, while grippy textured finishes lead on slip control—a matter of use case.
