![]() Possibly one of their other models may be a closer match. At the price quoted, I'd be tempted to try it (other suppliers may be available, I just searched "Swordfish 40807" ). ![]() I may have made a mistake in counting the gear teeth, and the measurements may not be absolutely precise, but it seems pretty close apart from the cutter diameter. Just measured mine, a Swordfish Curve for which this is the replacement blade, and the dimensions are: If the reduction in diameter was an issue the mounting could be packed down by a suitable amount The reduction could be done by rotating against a file or a stone perhaps. Hence, my comment above about how far the pencil goes in ![]() With a smaller diameter the pencil will just go further into the unit. If done on the correct rotation it may leave a tiny burr but that would not be such a bad thing as it would be in the correct direction. That should take the rounded corner off & leave a square, sharp edge. Therefore, instead of trying to grind the flutes why not put the cutter in the lathe & reduce the outside circumference by a thou. But thinking it through & how it works, I would think that because the cutter sits at an angle the tip of the pencil does not actually reach the end of the cutter. If it is not cutting it is because the corner of the top to the vertical cutting edge has rounded- i would think that is stating the b.g obvious. I know little of these things so forgive me if this is rubbish Never ceases to amaze/amuse mass variation of postal charges on items from t'other side of t'pond. Compared to the Caran d' Ache things at 10X the price, the x-acto one might be worth a punt.Ĭan you turn the cutters end for end - may make a difference ? The internals of the inexpensive x-acto one at the Canadian retailer's link below would probably be a very close match to the cutters./ gears of the one in the OP's picture. This type of sharpener shown by the OP was made by Boston in the US but are now or were made in China under different brands. One Boston and one Gillott, in the UK as well as a spare pair of blades in the US There's a couple of candidates on eBay at the moment I obviously don't know if they will fit but with the sentimental attachment worth a punt and may be capable of modification to fit. Caran d' Ache helical cutter replacement on Amazon UK (should I have mentioned this) Google make of machine as above and add spare parts. Jakar - well know auction site spares listed. Looks like a job for a VERY good man and a clarkson air bearing flute grinder ! Noel See how you get on with a diamond file first and if it really is too slow then think about a small wheel.Ģ Questions How hard is it to crank without a pencil in place? Gear looks messy, have you tried a little lubrication? That gives you a very defined face to work against. I would work on the flutes rather than the outsides of the cutting edges. May not be that hard to sharpen actually. I know most retailers/suppliers wont reply if I ask the dementions of their replacement cutters. Yep bit of a long shot, however I am sure some company is still using the same spec cutter. ![]() You might be better off to sharpen the cutting edges with a small diamond file.Or a Dremel tool if you have a steady hand. Measurements of the cutter are 15.05mm x 38.75mm with an 11 tooth gear and 15 helical cutting flutes. The model is a Boston 200, made my Gillett and sons and it looks as though the blade is dull as its hard to crank.Īs far as I am aware these sharpeners are no longer made but there are other similar designs made by different companies and spare cutters.ĭoes anyone know of a suitable replacement helical blade, even if I have to canabolise another replacement system to fit? I was tasked to repair a helical pencil sharpener which had some sentimental value hence looking for suitable spares. ![]()
