Hey Scott...
No one has replied...so maybe no one knows.
I had a 179 Hilo I "accidently" bought at a sporting goods store. "Accident" cuz I didn't read the fine print on the clampack in where it was made. Well, I digress, and my opinion on that has been documented and Buck has made strides to clearly mark country of orgin on the package.
ANYWAY, having said that,
I really liked my Hilo. But, someone else was admiring it so I gave it to him. I used to wear it on my vest and this guy saw it and asked about it. He liked it, so I gave it to him (never drink more than two Budweisers...ok, maybe three...judgement goes out the window).
It didn't seem any thicker than a 110...just about 5/8"...but I may be wrong.
Just last week he showed me he still has it. He works construction and that puppy has been used...a ton. Almost brought a tear to my eye...but I am glad he has used it hard with no problem other than the pocket clip breaking off.
I see him somewhat often at a local watering hole...if no one replies sooner I check it out and report back here for ya.
Couldn't find the pic of my Hilo, but here is a pic of the last thing I cut with it. IIRC, I used the Hilo to scratch edit the sticker on the bartender's tip bucket in the pic:
