The upper blade of Winland's new professional aluminium ratchet pruner is made of high-carbon SK5 steel with a non-stick coating. The handles are made of a strong aluminium construction with a soft TPR grip. According to the company, the ratchet system with four settings ensures a cutting capacity of up to 20mm on branches. The sliding lock can be used by both right- and left-handed users. An oil sponge is included for cleaning blades after each use to extend the service life of the blades. https://winland.imb2b.com
