Razorsharp, at 315 Outram Road #01-03, Singapore 169074, sharpens kitchen knives up to 240mm by hand on Japanese whetstones for $10 a piece. The shop is on the ground floor of the Tan Boon Liat Building and opens Monday to Saturday from 10am to 6pm, closed on Sundays and public holidays. Drop a dull knife at the counter and it is usually ready in a few days; the shop takes any kitchen knife except ceramic.

A Japanese Knife Specialist Since 2002
Razorsharp was established in 2002, and its about page describes it as a Japanese knife specialist serving everyone from home cooks to food and beverage professionals. The shelves are dense with Japanese makers, among them Sakai Takayuki, Sakai Jikko, Yoshikane, Sukenari, Sugimoto and Tojiro, alongside Fook Kee Chinese cleavers, konro grills, cutting boards and bar tools.
The store's homepage shows choil shots, the view down the spine of a blade, of 240mm gyuto made by the Sakai craftsmen Yoshikazu Tanaka and Kenichi Shiraki. That is a good sign of who shops here: cooks who care about the grind of a knife, not just the brand. Sharpening sits naturally beside that stock, because many customers bring back the same knives they bought on the shelf years ago.
The Price Board, Line by Line
The posted sharpening menu is short and easy to add up. Basic edge sharpening by hand on Japanese whetstones costs $10 per piece for knives up to 240mm, and $15 for anything longer. Chinese cleavers and choppers cost $15, as do single-bevel Japanese knives such as deba and yanagiba. That makes Razorsharp one of the cheapest whetstone services in the city for a standard gyuto or santoku.
Beyond kitchen knives, scissors cost $15, an axe $30, and straight razors or kamisori are also on the list. Repairs to a broken tip or chipped edge, including restoring the distal taper, cost $5 to $25, and thinning behind the edge for blades up to 5cm tall costs $15 to $50. A return delivery service costs a $20 flat rate island-wide, and spending $80 or more on sharpening earns a free pair of poultry shears.
How the Edge Is Finished
The sharpening page gives more detail than most shops publish. Double-bevel knives are finished on Japanese waterstones between 400 and 5,000 grit, with the final grit chosen according to how the knife will be used and how well its steel holds a refined edge. A soft stainless knife for a busy home kitchen gets a different finish from a hard carbon-steel gyuto.
Single-bevel knives sent to Razorsharp are taken up to 10,000 grit, so that a one-sided 15-degree grind can perform at its best. Thick knives are thinned along the blade face, and a hamaguri, or clam-shell, bevel is kept so that food slides off. For damaged knives, a 60-inch belt sander handles major chips and convex grinds before the edge is finished on stones again.
What They Take and What They Refuse
The shop sharpens any kitchen knife except ceramic, plus a long list of edged tools: scissors, straight razors, plane blades, chisels and axes. Bring the ceramic knife home again, because there is no service for it here. Serrated bread knives are not mentioned on the price board, so ask before handing one over rather than assuming it will be done.
Broken tips are ground back to a point without changing the edge profile, and the page notes that a repaired tip ends up stronger than the fragile original. My honest view is that the thinning service is the one to skip unless you need it: at up to $50 it costs more than most home knives are worth, and a standard $10 edge will transform a knife that is only dull.
Timing Your Drop-Off
The shop's own phrase is that a dropped-off knife is ready to slice and dice in a few days, so do not plan a same-day turnaround. A weekday drop-off at opening time is the calmest, because Saturday brings home cooks who work during the week. Remember that the counter is closed on Sundays and public holidays, which matters over long weekends such as Deepavali.
If you cannot come back to collect, the $20 island-wide return delivery is worth considering for a bag of several knives, since it costs less than two taxi rides across the island. For a single knife, a second trip combined with lunch in Tiong Bahru is better value. Wrap each knife in a cloth or a saya and carry them in a bag on the bus or MRT.
Who You Will Meet at the Counter
The shop says it serves everyone from modern homes to food and beverage professionals, and the price board reflects both: a $15 line for Chinese cleavers sits next to the $10 line for a home gyuto. The Tan Boon Liat Building is otherwise full of furniture and design showrooms, so the knife shop stands out on the ground floor: a small room of glass cases and stones among the sofas and lighting stores.
If the counter is busy and you only have a few minutes, hand over the knife, explain the problem in one sentence and collect a receipt. Staff can talk at length about steel and makers, but a quick drop-off is normal. If you would rather wait for the work, Binlin Knife Store in Chinatown sharpens on-site, from $12 for a petty knife, though it is closed on Sundays too.
Tiong Bahru and Outram on Foot
Outram Road runs along the edge of Tiong Bahru, so a drop-off fits neatly into a morning in one of Singapore's most walkable estates. The pre-war Art Deco flats around Seng Poh Road and Eng Hoon Street, with their curved balconies and spiral back stairs, are a short walk away. Tiong Bahru Market's hawker centre upstairs is the classic place for chwee kueh, lor mee or a kopi.
For a greener detour, Pearl's Hill City Park sits a little east, above Outram Park MRT, with a quiet path around its old service reservoir. Havelock MRT on the Thomson-East Coast Line is also close to the Tan Boon Liat Building. If you are collecting knives, keep them in your bag and visit the shop last before heading home.
