A blues harmonica is usually a 10-hole diatonic in the Richter tuning, the layout that lets players bend notes for the classic wailing sound. The key of C is the common starting key, and a full set of keys is added later. Comb material, reed plates and the cover design differ from model to model.
The six harmonicas below are all key of C, and each listing was opened for details. Specs are the makers’ own descriptions. We have not played these harmonicas ourselves, and where a listing contradicts itself we flag it.

The 6 Best Blues Harmonicas
1. Hohner Special 20
A key of C diatonic with an injection-molded plastic comb and a projecting mouthpiece, listed as responsive and for professionals. The material field says stainless steel, which describes the covers rather than the comb. Hohner gives a 90 day warranty.
Suits: a plastic-comb harmonica that is common in many styles. Strengths: a molded comb and a classic design. Weaknesses: the listing says little about extras. Skip it if you want a wood comb.

4. Lee Oskar Major Diatonic
The 1910-C in standard blues tuning with a plastic comb with large holes, an air-tight design and replaceable reed plates, which the maker says are a smaller outlay to replace than a new harmonica. A case is included. One field names the item as key of G, so confirm the key before you buy.
Suits: a player who may wear out reeds. Strengths: replaceable reed plates. Weaknesses: a key mismatch in the listing. Skip it if you want a wood comb.

5. Fender Blues Deluxe
A 10-hole key of C harmonica with chromed metal covers, brass reeds and a case. Fender gives a one-year warranty. One bullet calls it chromatic and another says the comb is molded PVC while a third says ABS, so the listing is not consistent. The title and highlight describe a 10-hole diatonic.
Suits: a recognizable brand for a gift. Strengths: chrome covers and a case. Weaknesses: contradictory listing details. Skip it if you need a clear comb spec.
