D'Andrea390 Sharkfin Delrex Delrin Guitar Picks - One Dozen Blue 1.0 mm
1/4
Independent shopping perspective
The Korena take
A dozen 1.0mm sharkfin picks in Delrin. The stiff gauge and multi-edge shape suit players who want a firm attack and optional string-raking edges.
Strong match
Who this is for
- Lead playing and single-note lines that need a stiff, precise tip
- Players who use the serrated edge for scraping and rake effects
- Heavier picking styles where thin picks flex too much
Consider the trade-offs
When to look elsewhere
- Light acoustic strumming, where 1.0mm feels stiff and clacky
- Players who want a familiar standard teardrop feel
- Anyone who finds unusual pick shapes distracting mid-song
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
One pointed tip for precision plus wavy, serrated edges you can drag across wound strings for a scratch effect.
Detail 03
Delrin (Delrex) material
Slick and wear-resistant. Releases off the strings cleanly with less pick noise than nylon at the same thickness.
Detail 04
Multiple usable edges
The sharp tip, a rounder shoulder, and the ridged side each give a different attack from the same pick.
Detail 05
One dozen per pack
Twelve picks. Worth having several since the shape is easy to lose track of by feel in a pocket.
Final check
Know before you order
- 011.0mm is a real jump if you currently play 0.60mm or thinner
- 02Delrin is smooth; sweaty hands may want a gripped or textured pick instead
- 03Blue is the color for this gauge here, so you do not pick color separately
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the serrated edge for?
Dragging along wound strings to make a scraping, ratcheting sound. It is a deliberate effect, common in rock and metal, not something you hit accidentally.
02Is 1.0mm too thick for strumming?
For soft acoustic strumming, yes. It has little flex, so chords come out harder and more percussive. Better for rhythm parts you want tight and punchy.
03How does the sharkfin compare to a standard pick?
The tip is more pointed than a standard 351, giving a sharper attack. The body is larger with several distinct edges rather than one playing corner.
04Do these wear out fast?
Delrin is one of the more wear-resistant pick plastics, and at 1.0mm there is plenty of material. The tip will round off eventually with heavy use.
