Japanese Knives
Petty vs Paring Knife
What this is based on: published manufacturer specifications and retailer listings, cited on each product; the weight of professional and owner reviews across multiple retailers; and hands-on experience sharpening and cooking with knives of this type. We have not individually tested every model listed, we do not run instrumented sharpness testing, and we do not claim a test we did not run.
Quick picks
| # | Product | Best for | Score | Price |
|---|---|---|---|---|
| 1 | Tojiro DP Santoku 170mm (F-503) | A second Japanese knife on a budget | 8.4 | |

| 3 |  MAC Professional 6.5" Santoku (MSK-65) | Precision vegetable work | 8.5 |
| Paring knife | Petty | |
|---|---|---|
| Length | 75–100mm | 120–150mm |
| Used | In the hand, off the board | On the board |
| Typical tasks | Peeling, hulling, coring, deveining | Trimming, segmenting, slicing shallots, portioning |
| Blade height | Low — around 20mm | Higher — around 25–30mm |
| Knuckle clearance | None needed | Marginal, so keep a pinch grip |
Which one is your kitchen missing?
Two diagnostic questions:
- Do you peel apples in your hand? If yes and you are using a 120mm blade to do it, you want a shorter paring knife. Long blades are awkward and unsafe for in-hand work.
- Do you reach for your chef's knife to slice one shallot? If yes, you want a petty. A 210mm gyuto for one shallot is a lot of knife to wash.
The case for a petty
The petty is the knife most home cooks do not know they want. It handles every small board job — trimming fat, segmenting an orange, splitting a chili, slicing garlic — without the bulk of a chef's knife and with far more control than a paring knife on a board.
It is also a low-stakes purchase. A petty does light work, which means the steel matters less, the edge lasts longer between sharpenings, and you do not need to spend much.
The case for a paring knife
Nothing else does in-hand work. Hulling strawberries, coring a tomato, peeling a stubborn potato that the peeler cannot handle, deveining a shrimp — these want a short blade you can control with your thumb close to the edge. A 150mm petty is genuinely dangerous for that.
Buy the cheap one. A paring knife gets lost, gets thrown in the dishwasher by somebody, and gets used to open packaging. It is not the place for good steel.
The verdict
Own a cheap paring knife and, if you cook most days, add a petty. The picks below are the closest widely available Japanese blades in and around the small-knife size class — a 170mm Tojiro DP santoku and a 6.5-inch MAC santoku both work on a small board where a 210mm gyuto is clumsy. We have not listed a specific petty model because the mainstream US stock in that size shifts frequently and we will not name a product we cannot confirm is currently sold. Buy the shape from a retailer who lists the steel and the hardness.
The picks in detail
#1 · A second Japanese knife on a budget
Tojiro DP Santoku 170mm (F-503)
The gyuto's sibling: same VG-10 san mai, same price bracket, shorter and flatter. The cheapest honest route into a Japanese santoku.
What it does well
- Same steel and geometry philosophy as the F-808 gyuto
- Light and easy to control for shorter cooks
- Inexpensive enough to learn stone work on
Where it gives way
- Plain finish, same as the rest of the DP line
- 170 mm limits you on anything large
- Soft cladding scratches quickly
Skip it if: Anyone who already has a 210 mm gyuto and a small board — the overlap is large.
| Blade length | 170 mm |
|---|---|
| Steel | VG-10 core, three-layer stainless cladding |
| Hardness | 59-61 HRC |
| Handle | Western composite wood with bolster |
#2 · A beater, or a sanity check before you spend more
Victorinox Fibrox Pro 8" Chef's Knife
Not a Japanese knife and not pretending to be. It is the control sample: if your cooking does not improve after upgrading from this, the knife was never the problem.
What it does well
- Stamped, light and genuinely non-slip when wet
- Soft enough that a pull-through sharpener will not destroy it
- Costs a fraction of everything else here
Where it gives way
- 56 HRC means frequent honing and frequent sharpening
- 18-degree edge is blunt by Japanese standards
- No bolster, no heft, no presence — it feels like a tool because it is one
Skip it if: This site's usual reader. At 56 HRC with an 18-degree edge it is a softer, blunter tool than anything else on this page.
| Blade length | 8 in |
|---|---|
| Steel | X55CrMo14 high-carbon stainless |
| Hardness | 56 HRC |
| Edge angle | 18 degrees |
| Weight | 5.6 oz |
| Handle | Fibrox Pro thermoplastic elastomer, no bolster |
#3 · Precision vegetable work
MAC Professional 6.5" Santoku (MSK-65)
The MTH-80's logic in a santoku: thin, light, 15 degrees per side, and consistent from unit to unit.
What it does well
- Extremely thin behind the edge for its price
- Same 15-degree factory geometry as the rest of the Professional line
- Light and neutral in the hand
Where it gives way
- Thin tip is easy to damage
- No bolster to protect your knuckles in a heavy grip
- Costs more than the Tojiro equivalent
Skip it if: Heavy jobs. It is thin, and thin blades dislike bone and frozen food.
| Blade length | 6.5 in |
|---|---|
| Steel | Sub-zero tempered high-carbon molybdenum vanadium alloy |
| Hardness | approx. 61 HRC (MAC Professional line) |
| Edge angle | 15 degrees per side |
