, it is interesting that a lot of scientific research has gone into the design of linerless G10 knives and many manufacturers design and sell their actual hard use knives made this way. I used to be in the liner only camp, but after researching, I found that in a folder, if it is well constructed, linerless G10 is as strong as linered G10. Science. The pivot pin for the lock is not a stress point to any significant degree. If you look at broken hard use knives, the weak liner locks fail at the lock. The very strong back locks fail at the blade, not the lock.
OK, let's do a scientific "Gedankenexperiment" then:
Take both a G10 scale and a steel liner of some old user Spyderco and do the following:
1) drill a hole in both. You might break your drill bit with the steel liner (has happened to me); on the other hand, the drill will go through G10 like butter.
2) put either in a bench vice, and try to bend them. The steel scale will bend under some pressure, and stay bent. The G10 will be elastic, always go back to it's original shape, until it breaks.
So, after this experiment, we realize that the steel liner is harder (HRC > 55?), but in some ways, G10 is tougher. Let's forget about the lock. My biggest worry is the main Pivot. Ovaling out, damaging it when scratching loktite out, etc. To make matters worse (drool-factor?), Spyderco decided to counter-sink the Chief's Pivot screws, making the effective Pivot/scale contact area even smaller/thinner. And yes, the Pivot screws counter-sunk or not add some contact area, but you want the blade to move, right ? In many other LW knives, Spyderco uses a washer on the outside to protect the scale, plus a flat head Pivot screw. Not here. Note also that I love D-shaped Pivots in my Military, Police, etc, since I only need one driver to adjust a blade. I wouldn't trust a D-shaped hole in a G10 scale for this purpose. Etc.
I'm sure the Chief will be great for many, you can flick it all day, cut some boxes, use it for SD (it only needs to work once), make some sandwiches, etc. Just not for me, who uses knives for weeks during camping, cleans his knives around once a year, etc.
And that's my last comment on this, don't want to spoil the group's excitement too much ... compliments to Spyderco on the new design, it's really pretty.
