Five-stroke metal radical on the left, the side form of 金. 锋 means the cutting edge or sharp point of a blade — a thing made of metal. Same radical groups 锋 with 钢 steel, 银 silver, 铜 copper, 锐 sharp, 钉 nail, all metal-family chars.
Right side 夆 supplies the sound — féng to fēng, a simple tone shift. The same phonetic series gives 峰 mountain peak, 蜂 bee, 逢 to encounter, 缝 to sew — all sharing the f-ng frame. A useful family to memorize together once you spot the pattern.
