X-ACTO School Pro 1670X vs Bostitch EPS4-BLUE: Which Pencil Sharpener Fits Your Desk?

For colored pencils and a wider documented size-selection routine, the X-ACTO School Pro has the clearer fit. For standard pencils on a personal desk, the Bostitch is a compact option that the independent guide operated one-handed. Its manual describes removing the pencil after sharpening; that is not proof it lacks a point-stop feature. Neither source set establishes better sharpening quality or longer cutter life in this exact comparison.

The buying question

Do you need a documented fit for colored and different-size pencils, or a compact sharpener that the tested Bostitch model could operate one-handed with standard pencils?

X-ACTO documents a six-size dial, colored-pencil compatibility and a flyaway cutter; Bostitch documents an 8.38 × 4 × 4.25-inch personal unit and its test guide reports one-handed use with standard 8 mm pencils. The sources do not establish a comparative sharpening-quality winner or prove that Bostitch lacks a point-stop feature.

Quick verdict

Choose Bostitch Personal Electric Pencil Sharpener (EPS4-BLUE, Blue) if

  • You mainly sharpen standard pencils and want a compact model; the manufacturer lists its body at 8.38 × 4 × 4.25 inches.
  • One-handed operation matters: TechGearLab reports that the tested Bostitch Personal stayed put during one-handed use.

When the recommendation changes
  • If your pencils are all standard size and you do not need a documented colored-pencil fit, either may fit; choose based on the operating routine and exact desk space.
  • If automatic stopping at the desired point is mandatory, X-ACTO documents that behavior; Bostitch’s manual gives an insert-start/remove-pencil routine but does not say whether it has an equivalent point stop, so verify that feature before relying on it.

The differences that matter

Pencil Size And Media Fit

X-ACTO School Pro Electric Pencil Sharpener (1670X, Black)

Six-size dial; colored-pencil compatibility is described for the School Pro family. The selected model is 1670X, but this page does not print that part number.[1]

Bostitch Personal Electric Pencil Sharpener (EPS4-BLUE, Blue)

The EPS4/EPS5 manual warns against crayons and chalk. TechGearLab reports that its Bostitch Personal sample handled standard 8 mm pencils and did not handle colored lead.[3, 4]

What this changes: If colored pencils or a range of pencil sizes matter, the X-ACTO has directly documented fit guidance. If your supply is standard pencils, the Bostitch test supports that narrower use. Do not extend the Bostitch manual’s crayon/chalk warning to every specialty pencil.[1, 3, 4]

The better fit depends on your priorities

Sharpening Completion And Bin Care

X-ACTO School Pro Electric Pencil Sharpener (1670X, Black)

X-ACTO says its flyaway cutter stops sharpening at ideal sharpness and its SafeStart motor stops shaving when the XL bin is removed.[1]

Bostitch Personal Electric Pencil Sharpener (EPS4-BLUE, Blue)

The EPS4 manual says inserting a pencil starts the motor and instructs users to remove a sharpened pencil; the product page says its safety switch prevents operation when the tray is removed. TechGearLab observed one-handed use and messy emptying when the tray was full.[3, 2, 4]

What this changes: The X-ACTO has an explicit point-stop description. The Bostitch sources describe an insert/remove operating sequence but do not establish whether it has an equivalent point stop. The guide’s one-handed observation may suit a personal desk routine; its messy-full-tray note is a limited test observation, not a measured emptying-frequency difference.[1, 3, 2, 4]

The better fit depends on your priorities

Best for your routine

A buyer regularly uses colored pencils or switches among pencil sizes.

Best fit: X-ACTO School Pro Electric Pencil Sharpener (1670X, Black)

Based on listed features, not comparative testing.

The School Pro manufacturer page documents colored-pencil compatibility and a six-size dial; the Bostitch manual cautions against crayons and chalk, while its test result is limited to standard pencils and colored lead.

A buyer mainly sharpens standard pencils at a personal desk and values a one-handed operating routine.

Best fit: Bostitch Personal Electric Pencil Sharpener (EPS4-BLUE, Blue)

Based on listed features, not comparative testing.

The Bostitch is marketed and dimensioned as a compact personal model, and TechGearLab observed one-handed use. This is not a claim that the X-ACTO cannot be used one-handed.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If current offers differ, weigh the X-ACTO’s documented colored-pencil and size-selection fit against the Bostitch’s compact personal form and tested one-handed routine; recheck the exact color and model at purchase.

There is not enough price history to recommend buying now or waiting. Compare current offers for the exact 1670X and EPS4-BLUE listings.

Limitations

  • The exact listing identifies this item as 1670X; X-ACTO’s School Pro page describes family features but does not print that model number.
  • TechGearLab notes that the X-ACTO sample it tested was updated after testing, so its measured X-ACTO results are not applied to this selected 1670X. Its Bostitch section links to the selected Bostitch Personal listing.
  • The sources do not establish a comparative sharpening-quality, noise, durability, cutter-life, or emptying-interval winner. Bostitch’s instructions do not establish whether it has an equivalent point-stop feature.
  • The X-ACTO source does not provide a footprint or voltage for this exact listing; no footprint, outlet, or bin-capacity comparison is made.
  • Offers change, and there is not enough price history to identify a typical price or advise buying now versus waiting.

Questions shoppers ask

Can I use colored pencils with both?

X-ACTO says the School Pro is compatible with colored pencils. TechGearLab reports that its Bostitch Personal sample did not handle colored lead and was suited to standard 8 mm pencils. The Bostitch manual specifically warns against crayons and chalk; do not broaden that warning beyond what it says.

Does the Bostitch automatically stop when the point is sharp?

The EPS4 manual says pencil insertion starts the motor and instructs you to remove the sharpened pencil. It does not describe a point-stop mechanism. X-ACTO explicitly describes a flyaway cutter that stops at ideal sharpness. If that feature is decisive, verify Bostitch’s behavior before buying rather than treating the manual’s silence as proof it lacks one.

Methodology and sources

Compared official pencil-fit and operating instructions for the selected product identities, then used the independent guide only for the Bostitch sample observations it reports. The guide notes its tested X-ACTO was updated, so those X-ACTO measurements were excluded.

AI assisted with source review and drafting. Pickoryx did not test either sharpener.
