1/4
Independent shopping perspective
The Korena take
A dozen .73 mm Delrin sharkfin picks in yellow. For players who want multiple tip options and a grippier, harder material than celluloid.
Strong match
Who this is for
- Players who want a sharp tip and a rounded tip on one pick
- Sweaty hands that slip off glossy celluloid
- Rhythm playing where a mid gauge suits both chords and lines
Consider the trade-offs
When to look elsewhere
- Players who want a warm, soft celluloid attack
- Anyone wanting a heavy pick above 1 mm
- Traditionalists who dislike the sharkfin's unusual outline
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Sharkfin shape
Multiple usable edges: pointed tips for articulation, a serrated edge, and a broader edge for strumming.
Detail 03
.73 mm
Medium gauge. Enough give for open chords, enough spine for single notes without heavy flex.
Detail 04
Yellow
Color codes the gauge on this line, so .73 mm is easy to spot in a pile of mixed picks.
Detail 05
One dozen
Twelve identical picks, useful since sharkfins take practice to hold consistently.
Final check
Know before you order
- 01The sharkfin outline takes adjustment if you're used to a standard 351
- 02Single gauge pack, not an assortment of thicknesses
- 03Delrin sounds brighter than celluloid; not a like-for-like swap
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is .73 mm thin or medium?
Medium. It flexes on strumming but holds its shape for single notes. Thin picks sit near .50 mm, heavy picks above 1 mm.
02What is the point of the sharkfin shape?
It gives you several usable edges on one pick: sharp tips for precision, a serrated edge for a scrapier attack, and a wider edge for strumming.
03How is Delrin different from celluloid?
Delrin is harder and lasts longer, with a brighter, more defined attack. Celluloid is softer and warmer but wears down quicker.
04How many are in the pack?
Twelve.
