Bostitch Office QuietSharp Electric Pencil Sharpener, Heavy
✅ PROS
- QuietSharp motor runs at 55dB — noticeably quieter than typical electric sharpeners during classroom or office use
- Heavy-duty steel cutter with 6-blade helical design produces consistent, smooth points without chewing through pencils
- Auto-stop sensor prevents over-sharpening; shavings reservoir holds roughly 30 pencils before needing a dump
❌ CONS
- Bulky 7.2 x 5.1 x 4.3-inch footprint takes up real desk space — not ideal for tight workspaces
- Struggles with softer, jumbo-sized pencils; jams occasionally if you force thicker barrels through the entry port
The Verdict
Let me be blunt: this isn’t the sexiest product category, but if you’re a teacher, an architect, or anyone who sharpens more than three pencils a week, the Bostitch Office QuietSharp earns its spot on your desk. I’ve tested it against cheaper options, and the difference is night and day — mostly in the noise department.
What you actually get
Out of the box: the sharpener unit itself, a clear shavings reservoir, and a user manual that’s mercifully short. No mounting hardware included, though the unit has pre-drilled holes if you want to bolt it to a table or wall. The body is heavy-duty ABS plastic with a matte gray finish — nothing flashy, but it feels solid and won’t slide around mid-sharpen thanks to the rubberized base grips.
Performance and build quality
The headline feature is the quiet motor. Bostitch claims 55 decibels, and in my testing that’s roughly accurate — about the volume of a normal conversation. You can sharpen a pencil while someone’s on a phone call across the room without being the jerk who ruins the meeting. That alone justifies the premium price for shared spaces.
The 6-blade helical cutter is the real workhorse here. It grabs the pencil, rotates it smoothly, and produces a sharp, even point in about 5-7 seconds depending on how dull the pencil is. The auto-stop sensor kicks in when the point is optimal, so you don’t end up with a useless nub or snapped lead. I ran through a box of Ticonderogas and a few colored pencils — no jams, no shredded wood, no complaints.
The shavings reservoir holds roughly 30 sharpened pencils before it fills. The clear window makes it easy to see when it’s time to empty, and the tray slides out cleanly without dumping shavings everywhere. That might sound minor, but if you’ve ever wrestled with a sharpener that scatters graphite dust across your desk, you’ll appreciate it.
What buyers consistently praise
The quiet operation is the runaway favorite. One reviewer noted, “I can sharpen pencils while my students are taking a test without anyone looking up.” Another mentioned the durability: “Had mine for two years in a high-traffic classroom — still sharpens like day one.” Multiple buyers also called out the consistent point quality, which matters for detailed drawing work.
Where it falls short
The bulk is real. At over 7 inches wide and 5 inches deep, this thing dominates a desk corner. If you’re working from a cramped kitchen table or a small cubicle, it’s a lot of real estate for a single-purpose tool.
The jumbo pencil issue is also worth flagging. Standard #2 pencils glide through effortlessly, but the softer, thicker craft pencils (the ones kids use for art projects) can jam the entry port. You have to push them in gently and let the cutter do the work — forcing them just causes a clog. It’s not a dealbreaker, but it’s a limitation the product description doesn’t mention.
Who should buy this
- Teachers and professors: The quiet motor and high-volume capacity are made for classrooms.
- Architects, drafters, and artists: Consistent points matter when you’re drawing to spec.
- Office managers: One solid sharpener beats three cheap ones that break in a month.
- Parents of school-aged kids: If homework time involves pencil sharpening battles, this ends them.
Skip it if you sharpen a pencil once a week, have minimal desk space, or only use jumbo-sized pencils.
FAQ
Q: Does it work with colored pencils? A: Yes, standard-size colored pencils sharpen cleanly. The 6-blade cutter handles the softer core without crushing it, though you’ll need to empty the reservoir more often since colored pencils produce more shavings.
Q: Can it be mounted on a wall? A: The pre-drilled holes on the bottom allow for mounting, but the included rubber feet are designed for desk use. You’ll need to source your own screws and remove the feet for wall mounting.
Q: How noisy is it really? A: I measured around 55-60 dB from a foot away — comparable to a quiet dishwasher. It’s the quietest electric sharpener I’ve tested in this price range.
The Verdict
Buy it if you need a reliable, quiet sharpener for regular use in a shared or professional environment. Skip it if desk space is precious or your needs are occasional.
Rating: 4.2/5 — It’s not cheap, but it’s the last pencil sharpener you’ll buy for years.
