The MultiSAFE 860 is a valuable member of HEWER family. A traditional safety mechanism of spring loaded blade retraction is activated by withdrawing the thumb off the slide. Only then the blade retracts on contact loss with the material automatically into the knife body. An extra extended blade length of up to 40mm is particularly ideal for deep cutting work. An unique, patent-pending rotating design allows for accurate and precise cutting , in which an extention blade length can be adjusted in every one millimeter! An ergonomically, durable GFN slim handle is designed for friendly using in deburring, piercing, cutting, dressing, finishing, contouring, etc. A long, non-slip slider offers a high stability and the most comfortable in works.Thank you HEWER for offering both 30° and 60° angle of blades to finish all cutting, deburring and scratching applications.
