After much study of edge usage and how serrations interact with various tasks, I have formulated a concept for part-serrated knife blades the Mid-Serrated blade.
This is one of my protoype blades, a Boker Trance 42 for EDCing.
Talking to many of those in the knife industry while at IWA 2016 it seems that this is not something any manufacturer has thought to try and it was accepted as an interesting concept.
This thread is not to discuss the Pros/Cons of serrations, and I appreciate their extra cutting power, and would like the facility to use serrations for certain cutting tasks, but I dont think the compromise has to be so obvious. It occurred to me that there wasnt really anything preventing the serrations from being in the middle of the cutting edge where they would have less impact on my general use of a blade.
Of course this is based on my own use of different areas of the blade. For simplicity I've used three main areas of the blade, the heel, belly and tip. For each I have worked through all the tasks I regularly carry out and been able to put an estimate of how much use each area gets and the type of cuts I make when I prefer a plain edge. These are shown below.
So the purpose of this thread is to ask everyone for their approximate percentages of use for the heel, belly and tip portions of the blade and how well you think the 'mid-serrated' blade would work for you?
Please reply using:
Heel- XX%
Belly/Middle- XX%
Tip- XX%
If you have a couple of specific usage scenarios where these percentages will be very different, please post moe than one set of figures with a quick description of the tasks.
I have a more in depth write up here:
The Mid-Serrated Blade
The two testing prototypes a fixed blade and folder.
Initial results are extremely favourable. These mid-serrations almost disappear in use as they just dont get in the way. However when I need to cut rope or other fibrous material, they power their way through even though being in the middle of the blade limits the pressure you can apply.
Remember that this is not to suggest all part-serrated blades should have mid-serrations, but to consider it as another option when choosing whether to go for part/fully-serrated or plain edge.
