vaporlock Posted June 19, 2018 Share Posted June 19, 2018 Hi All, I stumbled upon this study, started to read and had to share. http://knifesteelnerds.com/2018/06/18/maximizing-edge-retention/ very interesting and an excellent effort. vaporlock this will be moved to the knife making section.

templehound Posted June 20, 2018 Share Posted June 20, 2018 Tough there is a difference between rigidly fixed blades in a machine and free hand led blades. ....the cutting test machine gives information about wearing resistance of the alloy / the steel...for precise non-dynamic cutting action but blades that are hold and used free hand experiencing a lot of different angles and stresses on the edge. It says very little about edge performance of hand knives, the knives we are dealing with the most Altough interesting.... Thanks for sharing!

vaporlock Posted June 28, 2018 Author Share Posted June 28, 2018 Hi Tempelhound, Agree, but I would think that to study edge retention when using a knife free hand would be difficult. too many variables to be able to draw conclusions. I was nevertheless less surprised by the fact that edge angle has a greater influence on edge retention than hardness. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 28, 2018 Share Posted June 28, 2018 I remember that the study of friction, tribology, could get really weird with perfectly smooth surfaces having higher friction than rougher ones under certain conditions...

Jclonts82 Posted June 28, 2018 Share Posted June 28, 2018 more surface area contact can mean more drag? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 28, 2018 Share Posted June 28, 2018 Yup the study I remember was with pulling wire through conduits. Quote Link to comment Share on other sites More sharing options...

Look up turbulators for aircraft wings Quote Link to comment Share on other sites More sharing options...
