The Lum Chinese Folders are lightweights. They weigh 2.6'ish ounces and have just enough handle to hide a slightly over 3" FFG leaf. It's a 4-finger grip but a lighter duty one in my experience.
The Barong has a similar "ethnic" look but is certainly a different animal all-together. The handle itself is ready for white-knuckle work let alone the massive leaf. Throw in a Krein job and it's almost a true 4" cutting surface!
One is a gentleman almite folder/leaf shaped razor and one is a G-10, steel lined, ethnic user that's quite a bit more tactical/HD.
Either one would fit in the office or the field...but they would definitely prefer their customary roles.
PS: I can't speak from a user perceptive for the Barong as it's slightly longer than legal carry for my state, but I'm a big fan of it regardless. If we had a "under 4 inch" rule it would be lifelong EDC most likely.
The Lum is the sharpest knife I own and has caused me to fall in love with ZDP. I'm starting to think "sharp" is a phrase for people who haven't used a ZDP-189 blade with a good edge before. I am also very sure that people who have the VG-10 version still have a serious
cutter though because of the profile/design of the knife. It sure isn't a saber grind.
