I have a Nickel Silver/"White Brass" bolster & liners 110 with G10 covers from SK Blades.
If there is any weight difference between it and one of my standard production brass bolster & liners and Dynawood(?) or brass bolster & liners and real Ebony 110's (circa 1973 2 dot with 440C, and a August, 2020 Web Special with S30V) it isn't enough to notice.
I'd
guess less than 5 - 10 grains; if that much.
If you carry it in the sheath on your belt as they are intended to be, you won't notice the 7.3 ounces (give or take a couple grains depending on how ... ummm ... "rambunctious" ... the person doing the sharpening, and final polish was on that particular example was) plus sheath weight.
I've had a 110 (or Old Timer 7OT, which weighs roughly the same ...
maybe a touch more) on my belt pretty much every day (including school and church days) since 8th grade, in 1968. I've never noticed the weight.
(I don't notice the weight of my cocked n' locked "Combat" or "Compact" size 1911 (and spare magazines), or J frame 6 inch revolver, when I had a J Frame, in a OWB or SOB holster. More than once, I've tapped my side to make sure it, and the 110/7OT was still there.
Maybe I'm just weird that way ...?)
(I never liked a IWB holster. Need a size or two bigger waist pants for them, and for
me, they didn't stay in place when I sat. I prefer belt loops, not clips. I found it "embarrassing" at best, when I sat and my holstered CCW pistol or revolver landed on the floor ....)
I don't know if there is a weight difference between the standard 420HC blade steel, and the other blade steels available in/on certain dealer's SFO's, or Custom Shop knives. (5160, CPM154, S30V, 440C, etc.) No doubt if there is, it would be measured in single digit grains, and is meaningless.
