If you mean the classic Boston KS, you mean a manual, hand-crank sharpener—not a verified current Bostitch model. The historical Boston KS is a useful reference for that style, but the sources available do not establish that an authentic Boston-branded KS is currently sold. For a sharpener to use now, compare current Bostitch Office models by workload, power source, pencil fit, safety features, and cutter replacement rather than assuming they are the same product.
What does “Boston pencil sharpener” mean?
The name most strongly points to the classic Boston KS, a manual sharpener described in an undated reference catalog. The catalog lists a steel receptacle, a guide for eight pencil sizes, and a pencil stop intended to prevent over-sharpening. That description is historical evidence, not proof of the specifications or availability of a product sold today. Reference catalog entry

Current Bostitch Office product listings cover a broader assortment, including manual, electric, battery-operated, rechargeable, handheld, and colored-pencil sharpeners. A Bostitch listing is a current alternative to consider, not confirmation of the Boston KS’s present-day retail status. Catalog selection, stock, and prices can change. Bostitch Office sharpeners

Which Boston-style sharpener should you choose?
| Option | Best fit | What to check |
|---|---|---|
| Classic Boston KS, if found | Someone specifically seeking the historical Boston hand-crank design | Confirm the branding, condition, pencil-size fit, and whether the item is complete; the undated catalog entry does not verify current availability or a current specification. Reference catalog entry |
| Current manual sharpener | A user who wants a manual option without relying on a vintage Boston listing | Check the exact model’s pencil compatibility, mounting or handheld design, and whether replacement cutters are available. Current Bostitch categories include manual sharpeners. Bostitch Office sharpeners |
| Plug-in electric sharpener | Routine sharpening at a desk or in a classroom where power is available | Match the model to expected workload; review safety, noise, bin capacity, and cutter replacement details when the manufacturer specifies them. Bostitch electric sharpeners |
| Battery or rechargeable sharpener | Portable use where a plug-in outlet is inconvenient | Check whether the exact model is battery-operated or rechargeable, along with pencil compatibility and maintenance. These categories appear in current Bostitch listings. Bostitch Office sharpeners |
For workload, Bostitch’s buying guide groups its products for light, moderate, and heavy use, with home, office, and classroom settings as examples. Use that as a starting point, then confirm the actual model’s intended use and features; the category alone does not establish that one sharpener will suit every classroom or studio. Bostitch buying guide
How to compare current alternatives
Start with how often you sharpen
For occasional home or desk use, a basic manual or electric option may be enough. For regular classroom use, look at the manufacturer’s moderate- or heavy-use guidance and the model’s stated safety and maintenance features. Bostitch’s guide presents usage categories, but it does not supply a single independent test that ranks every model for durability or workload. Bostitch buying guide

- Commercial grade pencil sharpener for high volume environments
- Dual helical cutters sharpen pencils with precision
- Mountable on wall, desk, or table with the included screws
- Adjustable to accommodate 8 pencil sizes
- Manual operation is easy for school children to use
Choose power and portability together
A hand-crank or handheld sharpener avoids dependence on mains power; a plug-in electric model suits a fixed work area, while battery and rechargeable models trade outlet access for the need to manage their power source. Bostitch’s current listings span these categories, but the best choice depends on the exact model and where it will be used. Bostitch Office sharpeners
Check pencil compatibility before buying
The historical Boston KS catalog entry describes a guide for eight pencil sizes, but that is not a specification to apply to modern alternatives. Verify that the current model accepts the pencils you actually use, especially if they are unusually thick, colored, or otherwise nonstandard. Bostitch lists colored-pencil sharpeners as a distinct category. Bostitch Office sharpeners
Rank #3
- NEVER STALLS – Powerful stall-free motor powers through even the dullest pencils without stopping, keeping students and office workers moving
- SAVES DESK SPACE – Compact footprint fits on any desk, shelf, or countertop without crowding your workspace
- SAFE BY DESIGN – Auto-shutoff safety switch disables the motor the moment the shavings tray is removed, preventing accidents
- LARGE SHAVINGS TRAY – High-capacity tray holds more shavings so you spend less time emptying and more time working
- STAYS SHARP LONGER – Hardened helical cutter (HHC) delivers 4X longer cutting life so you replace the cutter far less often than standard sharpeners
Weigh safety, noise, and waste-bin capacity
For shared settings, look for the manufacturer’s model-specific information on tray interlocks and motor noise, and check the bin size if it is stated. Bostitch describes tray interlocks and quiet motor technology on its electric-sharpener page; those features should not be assumed to apply to every model. Bostitch electric sharpeners
What performance claims does Bostitch make?
Bostitch says some school models use dual cutters for “75% faster sharpening.” The manufacturer’s page does not provide an independent test method in the retrieved product information, so treat that as a company claim rather than a verified comparison across sharpeners. Bostitch electric sharpeners

- 65% faster sharpening and a 6x longer cutter life
- QuietSharp motor for quiet, stall-free operation (under normal use)
- Tip Saver Technology prevents over sharpening and extends pencil life
- Safety switch inhibits operation when easy-clean shavings receptacle is removed
- Thermal overload protection increases motor life
For the SuperPro Glow specifically, Bostitch says it sharpens a new pencil to a point in under three seconds. This is the maker’s claim for that named model, not a general speed figure for all Bostitch sharpeners or Boston KS-style sharpeners. Bostitch electric sharpeners

Do not assume a replacement part advertised for a modern Bostitch sharpener fits a vintage Boston machine. Bostitch’s official materials identify replacement cutters for particular models, including QuietSharp Glow (EPS11HC) and SuperPro Glow (EPS14HC); compatibility is model-specific. Check the exact model and part number before ordering. Bostitch replacement-cutter information

- Pencil Sharpener for Colored Pencils and Graphite Pencils: This professional pencil sharpener will start sharpening automatically when you insert a pencil.

Great for graphite and colored pencils, such as Prismacolor Premiers, Derwent, Verithins, Faber-castell, Koh-I-Noor Progresso. Please note that it is not recommended to sharpen EXTRA SOFT CORE pencils as it may cause jams in blade.
- Commercial Pencil Sharpener: High efficiency, fast speed and heavy use make it an industrial and commercial pencil sharpener. It has two safety features. The pencil sharpener will stop working when the shavings box is removed or not closed tightly. When sharpening too many pencils at a time, it will overheat and stop sharpening. Non-skid food pads at the bottom make it more stable to sharpen.

Take out the pencil when the motor sound changes. It takes far less effort than other mechanical pencil sharpeners. If you are a teacher, this is a must for classroom.
The available sources do not verify fitment for vintage Boston gears or cutters. A listing that appears to offer a replacement gear is not enough to establish compatibility with a particular KS sharpener.
What is known about the Boston sharpener’s history?
Garland Pollard’s 2009 retrospective reports Boston’s founding year as 1899, a centennial sharpener in 1999, and a Boston Pencil Pointer price of about $6 in 1913. These are historical details reported in that secondary account; the 1913 amount is a nominal period price, not a modern value or buying benchmark. Garland Pollard’s 2009 account
