What it does really well is solve the problem of having to switch between long-nose and circlip pliers mid-job, especially in tight mechanical assemblies where you're working with retaining rings in recessed spots and need to twist and cut wire in same go—the 6" model handles that fine for smaller hardware, while the 8" gives you more reach for deeper fittings.
The head hits 56-62 HRC on the Rockwell scale, which is better than most combination tools for harder wire, and the body sits at 40-48 HRC so it flexes a bit under heavy torque without snapping, and that black oxide finish keeps rust off even if you leave it in a damp toolbox for a week or so.
We see these going mostly to guys doing building decoration and mechancial repair work, where you're pulling circlips out of housings one minute and twisting tie wire the next, and the arched shaft actually gives you better than a flat profile when you're working at an awkward angle.
Lead time is usually 20-25 working days on a standdard order, and the MOQ runs about 100 pieces per size if you're buying direct, though our company can mix the 6" and 8" on the same shipment (check stock availability first, as teh 8" sometimes runs a week behind).
Most buyers go with the 8" actually, because the extra length makes the circlip function easier on stubborn rings, but the 6" is better suited for electronics enclosures where you don't have much clearance—neither is ideal for heavy-duty automotive suspension work, just so you know.
