With Japanese quality materials, the LP-450 has a 15% thicker blade with a fluorine coating to reduce resin and sap build-up.
The blade is also replicable by just simply unscrewing it. It is ultra-lightweight at only 400g meaning that it is easy to use for long periods of time, even when working overhead.
The Chikamasa LP450 is a pruner that is powered by an anvil. In order to focus cutting force and offer stability when cutting through heavier branches or stems, anvil pruners contain a single cutting blade that shuts onto a flat edge, or anvil. Cutting harder plant material or decaying wood is a speciality of this design. 
Chikamasa is a Japanese brand that has been producing shears, snips, loppers, and other grading equipment for over 100 years.  The LP-450 is ultra-lightweight so it is easy to use for long periods of time, even when working overhead.
