The OED’s “Word of the Day” today is “strick.” Among its other definitions:
1. A bundle of broken hemp, flax, jute, etc. for heckling. Cf. STRIKE n. 2.
14.. Nom. in Wr.-Wülcker 696/12 Hic linipolus, a stric of lyne. c1440 Promp. Parv. 479/2 Streek, of flax (Kylw. A.P. linipulus). 1616 SURFL. & MARKHAM Country Farm V. xviii. 568 So you shall beate this flaxe till it handle as soft as any silke, then vnplat the strickes againe, and heckle it through the second heckle. 1673 A.

Heckling, here, not meaning “to taunt or make fun of,” but rather “to comb flax to straighten the fibers.”
This is the challenge/genius of the free “word of the day” on the OED. You can’t fall down the rabbit hole of definitions and etymologies, trying to get a handle on how these things are related, without paying for a sub. Fortunately, you can still fall down the rabbit hole of the Internet for free, and this was a cool find. I’ve never had a good grasp on ye olde fairy tale description “flaxen-haired” until now.
