There are 3 types of Sugihara Guidebar – Pro Laminated, Pro Solid and Light Type pro. Have a look at the second picture above in the gallery to see how these bars differ.
What makes a Sugihara bar so good? This is a difficult question to summarise easily.
Sugihara bars started manufacturing chainsaw bars in 1967 by Hideo Sugihara. Japan has always had a reputation for excellence forging and working steel. Having the knowledge to manufacture quality chainsaw bars is not something that is gained overnight. It is a complex process of which cutting out the initial bar is only one part.

Steel has different properties dependant on how it is heated then cooled. Sugihara bars may go through the process of heating and cooling up to 4 times on different parts of the bar in order to gain maximum performance. The rails need to be accurately cut and hardened but over hardening can make them brittle. The bar body needs to be stiff yet flexible. We have used a number of different chainsaw bars over the years including all the major manufactures. Sugihara bars are the hardest wearing bars out there. Even their laminated bars will outlast rivals.

On the single piece pro and light type bars the hardness of the rails is measured at HRC 60. Compare this to Stihl at HRC 57 and Oregon at HRC 55 and it is clear why these bars last longer. They are so hard they resist most flat files when it comes to bar dressing
