Sharpeners & Spares
This is a general guide to the main types of needle sharpeners. It is aimed at helping enthusiasts to use thorn needles, and above all to enjoy records!
We usually have a selection of original sharpeners for sale. Stock varies, so please email windupmerchant@madasafish.com and ask for a list of what we have available, or for advice.
All types of sharpener shown below are viable. Some are better or easier than others. They have become collectable in their own right and can sell for high prices elsewhere.
Needle socket diameters
Original abrasives were often surprisingly coarse. Perhaps this was so that needles were used up sooner, so more would be sold! They were usually glasspaper, but we recommend using 240 grade
Rubber wheels/tyres usually need replacing. Some types use a standard Singer sewing machine rubber wheel (for the bobbin winder mechanism); others require a rubber
Early type BCN
2 types – one metal with wooden handle, other Bakelite. |
Tyre: 9mm id x 3mm xs |
Late type BCN
These have a solid wooden block for the ‘anvil’. |
Tyre: 9mm id x 3mm xs |
IM Pointmaster
Most are Bakelite (in many different colours) but a minority produced during WW2 were
metal. |
Tyre: 9mm id x 4mm xs |
The tyre size for IMs can be particularly variable due to the design; the height of the abrasive surface (attached to a thick card strip) may also need slight adjustment. Note, we can supply special BCN needles in black to refill original IM “top hat” cartons.
Universal
2 types (the larger is shown).Tyre: Singer
In common with the RM, the larger version is the next best sharpener to the MAL in our estimation.
RM
Similar to the Universal shown above, but more squat in shape. Tyre: Singer
MAL
Made by the late Miles Mallinson in more recent decades, the MAL is in our opinion the best
thorn needle sharpener ever made, apart from the Expert. |
Tyre: Singer |
Meltrope – 2 types, the earlier/longer of which was sold as BCN’s first sharpener.
Kacti (U.S.) – also sold under various other brand names.
Expert – the absolute |
(No tyre) |
An innovative and superbly efficient design. A soft rubber facing on the spindle takes up drive from a running gramophone turntable. The only drawbacks are that it is easy to take off more material than necessary; and dust settling on the turntable and motorboard is undesirable. The abrasive is a grindstone which is highly unlikely ever to wear out.
Tyre set is available from Chunny in Australia – email chunnybh@gramophone.hk
