KastKing Radius KutR Line Spooler — Built-in Cutter, Compact Twist-Free Spooling

Spool Like a Pro — Without Line Twist

The KastKing Radius KutR Line Spooler is a compact, patented tool designed to simplify line spooling for both spinning reels and baitcasting reels. It works with monofilament, fluorocarbon, and braided lines, helping you move from filler spool to reel without introducing line twist or memory.

The KutR features a built in line cutter for quick trims after you spool, and an extra cutting cartridge stored inside so you’re never caught without a sharp edge. With adjustable tension bands and soft touch clamping points, you can tune the wind to fit your line type while protecting your rod blanks during setup. Built from durable ABS, the tool resists rust and stands up to frequent field use.

One of the most practical advantages is its 1/4 lb spool capacity, which accommodates common line sizes while keeping the setup tidy. The minimal, thoughtful design means you can quickly attach and detach, then stash the KutR in a tackle bag, glove box, or boat compartment without adding bulk.

Smart, Portable Design for Real World Fishing

The Radius KutR is purposefully compact. Its threaded T-handle stores inside the unit, and the tension band can be tethered to keep all components together. Rubber coated clamp points grip most rod sizes securely without marring the finish, so you can spool with confidence whether you’re at the dock, on a boat, or in the garage.

• Compact design that travels easily with your gear
• Threaded T-handle stores inside for convenient transport
• Rubber coated clamps protect rod blanks during setup
• Soft touch components minimize slippage during winding

How to Use and What to Expect

Using the KutR is straightforward: clamp to a rod, thread your line from the filler spool through the built in cutter, and crank the handle to fill the reel with controlled tension. The line is fed directly from the filler spool to the reel, helping reduce coiled memory and ensuring a clean transfer onto the spool.

• Attach to a rod, secure the spool, and align the line path
• Adjust the tension band to suit your line type
• Crank the T-handle to wind smoothly onto the reel

What You Get and Real-World Benefits

In addition to the core spooler, you receive a spare cutting cartridge and a durable, rust-resistant tool built for regular use. The KutR’s design aims to make line preparation faster and more predictable, so you can focus on casting and fishing adventures rather than setup.
