CRK fluorinated grease is a must have for the maintenance of any Chris Reeve folder. This lubricant not only enhances the ‘hydraulic’ smoothness CRKs are known for, but also protects the pivot from corrosion – offering peace of mind for those who cut foods or otherwise expose their knives to moisture. A recent discovery of ours at Magna Knives, CRK grease also provides an excellent feel on all Strider models.
