What the differences mean
At the 7-iron, the 639 CB is 32° and the 659 CB is 32°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 8 clubs both sets share, the differences roughly cancel out, with the largest gap at the PW (44° vs 45°). The pitching wedges are 44° and 45°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the 639 CB runs 3-iron to PW (8 clubs), the 659 CB 3-iron to GW (9 clubs).
Both are players irons, built for roughly scratch to 10 handicaps. Small-to-mid cavity backs with traditional lofts, modest offset and workable shaping for low-handicap players. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
The 639 CB is listed as forged from a billet with a CNC-milled back and the 659 CB as forged and CNC milled from a single billet. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The 659 CB arrived 3 years after the 639 CB, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept.
Which should you choose?
The 659 CB is the weaker-lofted set — up to 1° weaker than the 639 CB. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
