Having a partial serration, or combination edge, on a working or tactical folder allows for two things:
1. Utility - the partial serration provides an additional attribute to the knife by allowing aggressive and swift cutting of materials like thin flexible plastics, rope, synthetic cords and ties, light to medium rubbers, and leather.
2. In CQB or SD the partial serration provides additional aggressiveness to the blade for cuts, slashes, and powering out of a wound channel. This is particularly desirable as most folders have pocket sized blades to them, meaning 3.5" to 4". Not alot of heft or length to work with.
On fixed blades a partial serration is likewise preferred. That is why I wanted the partial serration on the 21st Century KA-BAR Fighting Knife and so described in my Paladin Press book on the same subject.
I, too, appreciate a fully conventional edge and own a few. However, my Emerson CQC7 from EK features a partial serration (carried during Operation Iraqi Freedom) as I wanted - for Reason #2 - that added "insurance" if necessary.
The new Pro Hunter EXTREME by Tim Wegner features Blade-Tech's new partial serration and it's way nice. Saw / handled the knife just before SHOT Show this year. Nice to see a tactical Pro Hunter available and about time
The SERE 2000 is greatly enhanced with a serration (partial) and I see it as a counter balance design to the fact that the original SERE was a much larger and more powerful tactical / survival folding knife than the 2000 is. The serration allows for Reasons #1 and #2, otherwise the 2000 is one of many very good designs and products of essentially the same size, weight, and materials coming from this catagory of folder today.
Trust this helps.
