What is the Sakura SumoGrip Pencil?
It is a mechanical pencil built around a triangular grip. Sakura of America says the specially designed, ergonomically correct contour is a natural fit for hands, and that the shape lets fingers feel relaxed and flexible. It adds that physical therapists recommend SumoGrip to carpal tunnel patients and adults with fine motor skill difficulty. That is Sakura’s claim; we haven’t checked it.

Who is the SumoGrip Pencil for?
It suits people who write or sketch for long stretches and want a wider, triangular grip.
Everyday writing: Sakura lists note taking, accounting and teaching writing, with refill erasers sold and prices from US$4.23 to US$7.54 at Blick.
Drawing and sketching: Sakura lists drawing, sketching and drafting, in refillable 0.5, 0.7 and 0.9 mm lead sizes.
Skip it if you want a metal drafting pencil: Sakura names no body material, and the grip is its selling point.
Which lead size should you pick?
Sakura gives a reason only for 0.9 mm. It says the 0.9 mm version withstands strong writing pressure because of the heavier lead and the clear, fixed lead sleeve, which makes it a fit for anyone who tends to press hard. The page gives no advice for 0.5 or 0.7 mm; thinner lines are simply what a smaller number means. For lead types and hardness, see our best mechanical pencils roundup.
How does the eraser work?
It is a twist-type eraser. Sakura calls it a jumbo twist eraser that lasts six times longer than the average pencil eraser, and says a 3-pack of refill SumoGrip pencil erasers is available. It does not give the comparison pencil or a test.
How does the price change with the lead size?
The 0.5 mm costs the most at Blick. On November 2, 2026, Blick listed the 0.5 mm at US$7.54 (item 22527-1005), the 0.7 mm at US$5.23 (20680-1007) and the 0.9 mm clear at US$4.23 (74107-1009). That makes the 0.5 mm US$2.31 more than the 0.7 mm and the 0.9 mm US$1.00 less. Blick lists the 0.9 mm as a separate “clear” item, so it may be a different edition from the other two; Blick does not say how.
What are the limits?
The page is short on dimensions. Sakura gives no length, weight, body material or lead hardness. Blick’s listing for the 0.5 and 0.7 mm models says they have a strong no-roll clip and the jumbo eraser, and its 0.9 mm entry is a separate item, the clear version. If you need to know the pencil’s weight or balance for long sessions, check it in a shop.
Where is it made, and what does it cost?
Sakura doesn’t say where it is made. Neither Sakura of America’s page nor Blick’s listing names a country.
At US$4.23 to US$7.54 depending on lead size at Blick (November 2, 2026), it is in our $$ band ($5 to $20); the 0.9 mm clear is just under it. Prices change; check the listing.
