Been fighting the flu (khuks don't help!) and coming in late on several posts here.
A few comments on this thread:
I have lived in crummy apts in my time, and while still a kid, had to confront intruders while armed with a knife, on one occasion an ice pick, and once with a small axe (hatchet.)
I am glad that I am better armed now, and the big knife near my bed is only the SECOND thing I reach for, if things go bump in the night.
The concept of a 'safe room' is all very well for those in suburban split levels and penthouses, but if your home is a two-room bed-sitter with an outside door accessible from the street, one wonders how the concept should be utilized. I chose to go to the threat, and successfully, as I am still here.
Stalking an intruder in the blind, through doors and around corners, is sport for tigers. For what it's worth, my take on corners (right handed defender) is to advance on left-corners with the left foot, knife hand low, supinated and 'cocked' to deliver a horizontal or rising blow/drawcut to the midsection. A right corner would be approached differently, right foot first, knife hand vertical by left shoulder for a downward strike. Keep the free hand close to the body, no sense in offering your opponent a handle. Other forms would undoubtedly work.
The khuk is a 'saber', not an epee. Cuts, not thrusts, are its forte. Keep all the distance you can while staying in range for your cuts. If your instinct is to thrust, you would be better armed with a 10-14" Bowie or dagger. In a 'chest to chest', I would try to disengage before striking, rather than grapple. (A short dagger is best for that sort of fun.) By the way, a solid blow with a heavy blade beats a surgical thrust every time, for immediate effect and incapacitation.
I find the 20" sirupati a bit cumbersome for this exercise, but the Gelbu Special, at the same weight and an inch less in length, seems good. I expect the BAS and WWII, 15" sirupati and AngKholas would serve as well.
