WHISE Patrik – single-finger trainer for strength & rehab Patrik is a compact single-finger trainer designed to strengthen and rehabilitate individual fingers. Use it with resistance bands or add weight for progressive loading—simple, effective, and easy to use anywhere. Made from mixed hardwood species, WHISE prioritizes reclaimed/off-cut wood whenever possible, and when that isn’t available they use FSC/PEFC-certified wood. The included 4 mm nylon (polyamide) cord is rated up to 400 kg and conforms to UIAA EN564. Small, sustainable, and practical—also a great keychain or gift for climbers. Why we like it at arrampica!
