== Lines of Cutting ==
A seam is a line of cutting that provides a potential opening in the receiver’s defenses that the feeder can exploit.
An open seam is when the receiver is not adequately protecting a seam and has left a gap in their defenses which provides the feeder with an entry point to a vital target
A closed seam is when the receiver is adequately protecting a seam and has left no gap to be exploited.
Today we focused on two methods of opening seams 1) Force on Force and 2) Force on No Force

=== Force on Force ===
The Feeder performs two actions of force to open a seam.

==== Drill 1 – TD1 #1 ====
1. Feeder performs #1 from TD1 (Palm up thrust to internal jugular on the receiver’s left side of their neck)
2. Receiver performs cross-body tap with right arm
3. Feeder clears the tap by pulling the receiver’s right forearm/wrist in to himself (towards shoulder/chest level) to begin opening a seam, and continues with intent to thrust to the internal jugular (FORCE #1)
4. Receiver is forced to perform a bad-hand block with his left arm, and the seam is now open.
5. Feeder makes contact with the block (FORCE #2), then redirects the blade to pass under the receiver’s elbow and back up to slash the the opposite-side jugular through the open seam.

==== Drill 2 – TD1 #2 ====
1. Feeder performs #2 from TD1 (Palm down thrust to external jugular on the receiver’s right side of their neck)
2. Receiver performs cross-body tap with left arm
3. Feeder clears the tap (from under his own blade arm) by pulling the receiver’s left forearm/wrist in to himself (towards armpit/chest level) to begin opening a seam, and continues with intent to thrust to the internal jugular (FORCE #1)
4. Receiver is forced to perform a bad-hand block with his right arm, and the seam is now open.
5. Feeder makes contact with the block (FORCE #2), then redirects the blade to pass through open seam and up to slash the the same-side jugular. Redirection is done with a wrist rotation to bring blade point down so that it will clear the receiver’s right forearm as the feeder slashes upward to target.

=== Force on No Force ===
The Feeder performs one action of force and one nonlinear action to open a seam.
1. Drills are the same as above, but feeder does not make contact with the receiver’s bad-hand block.
2. Feeder uses a non-linear movement to pass the blade through the receiver’s open seam.

=== Things to remember ===
* On the TD1 #1 feed: when pushing the blade through the open seam, the blade really needs to pass under the receiver’s left elbow rather than across the forearm in order to deny the receiver the opportunity to close his seam.
* A trained opponent may be able to track the blade all the way through the force on force pattern (even as you pick up the speed and intent, or in a free-flow context). This success on the receiver’s part can install a reflex that can be exploited on the next iteration by using the force on no-force pattern.
