I've been following Greg Ellifritz's insightful Active Response Training blog for years now, so when I heard that he was coming down to Florida for a weekend to teach some classes, I jumped at the chance to check it out. I was not disappointed. Here are my rough notes from each class, unedited:
Day 1 - Knife Skills for CCW
Introduction and Knife Selection
West Side Story-style
knife vs. knife combat is rare.
More common scenarios for using a knife in self-defense: (1) knife vs. unarmed but physically superior attacker, (2) knife vs. multiple unarmed attackers, (3) knife used for gun retention, (4) knife for rape defense, (5) knife for fighting in awkward close-range positions.
There's a wide range of students in class - including some total beginners.
Greg lectures a bit on knife selection - goes through fixed, folding, and automatic, along with demo of various locking mechanisms.
Greg's recommendation - carry a fixed-blade, non-serrated knife, that isn't too crazy big.
Targeting in this course is designed for blades around 3"-4" or smaller.
Greg hits on considerations of various carry methods and knife types, including discussions of common self-defense knives (Clinch Pick, TDI, Delica, etc.).
[I am using a Clinch Pick, a Kershaw/Emerson waved folding knife trainer in right pocket, a Blue Gun GLOCK 19, and a fixed blade trainer (left side)]
Grips, Openings, and Retention
We practice getting a grip on the knife - practice forward, reverse. Need to be able to use all grips since you never know how you might draw the knife.
We practice openings - thumb, inertia, 2-hand
Knife retention position - in forward grip, brace on hip; in reverse, can use other side or center chest area.
If knife arm tied up: (1) switch hands, (2) cut attacker hand, (3) bring hip to knife then thrust
Knife Targeting
Blood stoppage targets - carotid, behind collarbone, armpit, past hip muscle/top of femoral, femoral, brachial
Biomechanical targets - muscles/tendons at lower arm/wrist, bicep/tricep, back of knee, Achilles, quadriceps/hamstring, fingers/eyes
Wound enhancement techniques - pressure cut, "filet cut," coring (twist the knife), "comma cut" (stab, twist, cut out), running (pump blade up and down)
Krav Maga-style chokes/grapples defended with knife
Special Topics
Concealed knife positions (reverse grip palming, crossed arms, knife in pocket, bag over knife)
Using a knife with a gun (Harries-style)
Knife to retain gun (grab enemy wrist or tie up with elbow trap, then cut with free hand)
Ways to sneak knife into NPE (hide it where they won't wand, ceramic/G10 knife, hide in cellphone case, use belt buckle, walk through as fast as possible)
Day 2 - Tactical First Aid and System Collapse Medicine
"Tactical" First Aid?
Focuses on gun/knife wounds, hostile conditions, limited training/equipment
Unpreventable deaths - severe head or torso trauma
Preventable deaths - extremity bleed, tension pneumothorax, airway
MARCH algorithm (we're skipping head injury/hypothermia)
Direct pressure is first - can clamp with hands, use CPR position, use knee on wound
Problems with direct pressure - self-application, strength/endurance needed, takes up hands, limits mobility
Most GSWs do not involve spinal injury, so usually safe to move patient
Equipment
Pressure Bandages
Wound Packing
Tourniquets
Hemostatic agent (note that you need multiple yards to pack even a moderate wound - 2" wound requires 3-4 feet of gauze)
Emergency TQ removal - after 2 hours, if no help coming, can try to remove slowly if wound is bandaged up. If it bleeds, reapply TQ and leave it. After 6 hours with TQ on, do not remove - dead cells in limb produce toxins that can kill.
Airway - chin lift/jaw thrust + recovery position + NPA if necessary
Chest seals - note even a "vented" seal only works 10% of the time on a sucking chest wound
Opiate OD - use Narcan, open airway
Longterm, Austere, and Wilderness
Wound care - need tons of H20 to irrigate wound
North American snakes - clean up wound, do not TQ, elevate, keep heart rate down, take a picture of the snake, get to antivenom ASAP
Antiseptic plants like yarrow and dandelion
Close wound or not? - closing speeds up healing and minimizes scar, not closing is better for deep punctures and really dirty wounds
Superglue, sutures, staples
"End of the world drug list" - animal antibiotics, etc.
