The Mid-Range Crimper That Gets It Done

The Diamond Crimper sits between the budget AFW at $17.99 and the professional CH18 at $169.99. For most anglers who rig leaders regularly but not daily, this is the right tool. The hardened jaws produce clean crimps without the jaw play that develops in cheaper tools.

Consistency is what separates a good crimper from a bad one. Every crimp from the Diamond Crimper compresses the sleeve evenly, which means every crimp holds the rated strength. When your leader connection is a crimp holding against a 40lb yellowfin, consistency is not optional.

Hardened Jaw Quality

The jaws are hardened for durability and crimp consistency. They compress standard oval sleeves evenly without the jaw play that develops in softer tools after repeated use.

Standard Sleeve Compatibility

Works with standard oval crimp sleeves from all major manufacturers. Handles the range of sleeve sizes used in typical inshore and offshore leader rigging.

Dual Material Capability

Produces clean crimps on both wire cable and heavy monofilament leaders. The jaw profile works with the different sleeve shapes used for each material.

How to Crimp with the Diamond Crimper

1. Match your sleeve size to your leader material diameter

2. Thread the leader through the sleeve, form your loop, thread back

3. Seat the sleeve in the crimper jaws

4. Squeeze firmly for full compression

5. Check the crimp for uniform shape without cracks

6. Pull test both ends of the leader
