How to Tie the Olsen's UV Purple Blowtorch
- 1
Step 1
Secure the Umpqua Perdijig 210BL in the vise. Start the UTC 70D purple thread and wrap a thread base to the bend.
The Perdijig is a barbless jig hook — ideal for competition-style euro nymphing.

Step 2
Tie in a short tag of #2 Glo Bright Floss in fluorescent pink at the bend to create the hot spot tail. Trim to a short stub.
The hot spot tail should be very short — just a small bright tag visible at the rear.
- 3
Step 3
Tie in a length of UTC Ultra Wire in silver, small, at the tail tie-in point.
- 4
Step 4
Dub a tapered body with Hareline Ice Dub in purple, building from the tail forward to about two-thirds up the shank.
Keep the dubbing noodle tight for a slim, flashy body. The UV properties of the Ice Dub add extra visibility.
- 5
Step 5
Wrap the silver wire ribbing forward in evenly spaced turns over the dubbed body. Tie off and trim.
- 6
Step 6
Select one or two CDC feathers and tie them in as a sparse collar. Wrap one or two turns and tie off.
Keep the CDC collar very sparse — just enough to add movement and trap air bubbles.

Step 7
Switch to or tie in UTC 70D in fluorescent pink and build a small hotspot collar behind the hook eye. Whip finish and trim.
The fluorescent pink hotspot at the head matches the tail tag and adds a triggering visual cue.
