To maintain the performance of your Priston Tools, adhere to the following schedule:
Note: Priston offers official certified replacement chains and hooks. Never mix Priston components with third-party parts, as the metallurgy and heat treatment vary.
Priston Tools is not a centuries-old Swiss firm. Its origins lie in post-WWII Japan, a period when the country shifted from rebuilding to redefining quality. Founded in the industrial hub of Niigata, Priston initially produced dies and gauges for the automotive industry. priston tools
The pivot came in the 1960s. As Japanese watchmaking (Seiko, Citizen) began challenging Swiss dominance, they needed tools that could handle finer tolerances than Western alternatives. Priston answered by developing the world’s first interchangeable blade system for horological screwdrivers—a design later copied by every major brand.
Key philosophy: “The tool must disappear in the hand.” If you feel the tool, you are not feeling the work. To maintain the performance of your Priston Tools,
When you need precision positioning without electricity, the lever hoist is your best friend. Priston’s version features a unique “freewheel” mechanism that allows the operator to pull the chain manually to the desired hook point before engaging the ratchet.
Looking ahead, Priston is investing in digital integration and lightweight composites. The company is currently beta-testing a line of "Smart Chain Blocks" that feature load cells and Bluetooth connectivity, allowing a rigging supervisor to monitor the exact load weight on a smartphone app from a safe distance. Furthermore, new composite housing materials are being introduced to reduce the weight of 5-ton chain blocks from 45kg to under 30kg, reducing operator fatigue.
