Casting model

This batch entry combines two distinct offshore boat casting series from Major Craft's Giant Killing lineup: the GK1 (1G grade, entry-level) and GK5 (5G grade, upper-mid). Both are offshore saltwater casting rods designed for boat-based pelagic fishing -- made for yellowtail, amberjack, Spanish mackerel (sawara), bluefin tuna, GT, and similar species using poppers, diving pencils, and metal jigs. These are not freshwater or inshore rods. The target angler fishes from party boats or private vessels in Japanese coastal waters or equivalent offshore environments.

GK1 uses intermediate-modulus (torque-focused) carbon in a down-lock reel seat configuration; the design philosophy emphasizes fatigue reduction and forgiving action over all-out sensitivity. GK5 uses Toray T1100G (the strongest in Toray's lineup) with R360 multi-directional carbon layup, made for a performance tier significantly above GK1 in blank stiffness-to-weight ratio and casting precision. Both series use Fuji K-frame SIC guides. GK1 is priced at approximately 18,000-22,000 JPY; GK5 at 37,000-45,000 JPY, reflecting the blank material difference.

The 17 combined models break down as 11 GK1 casting models (including 3 new 2-piece center-cut variants added June 2026) and 6 GK5 casting models. GK1 lengths run 6'7"-8'2" with R and RF actions; the 6'7" and 7' models handle up to 50-60g lures for lighter inshore pelagics, while the 8'2" heavy models (power ratings 5-8) handle up to 160g for large tuna and GT. GK5 runs 7'4"-8'2" RF action only, with blank weights from 134g to 310g and higher drag ratings than equivalent GK1 models.
