Made of 6061 Aircraft Aluminum these Marlin spikes will get the job done for years to come without the hefty price tag of other metal cost. I finish all spikes to a very high 2000 grit polish. Gently slide the tip under the strand you need to tighten and give a tug. These are made to order so turn around time is 1-2 weeks. All are finished to a very high polish. Spike will come without a lanyard hole but there is an option for adding one.
