Thanks to its high-quality stainless steel build, the knife maintains sharpness over time and resists corrosion, ensuring long-term reliability. For home cooks who want both performance and presentation, this tool turns a tedious chore into a satisfying experience.
In real-world testing, the Hong Won knife sliced through raw sweet potatoes like butter, producing consistent crinkle cuts ideal for even cooking and crispiness. The 4.5-inch blade offers enough surface area for efficient chopping without feeling unwieldy, and it handles softer vegetables like cucumbers and carrots with equal finesse. While it excels on most produce, extremely fibrous root vegetables occasionally required a firmer push. Cleaning is straightforward—food doesn’t cling to the blade thanks to its smooth, polished design—and it fits neatly in standard knife blocks or drawers.
Compared to the ZYLISS model, it offers nearly identical performance but with a slightly more minimalist aesthetic and comparable ergonomics.

For those seeking a no-nonsense, high-performance crinkle cutter that handles sweet potatoes with ease and elevates meal prep across the board, this model delivers superior craftsmanship and consistent value.

Each knife features a deep-ripple stainless steel blade that powers through sweet potatoes with ease, creating eye-catching crinkle cuts that cook evenly and crisp up beautifully. The solid wooden handles provide a natural, non-slip grip that feels balanced and sturdy—uncommon at this price point. With two included, you can prep multiple ingredients simultaneously or have a backup ready, making it ideal for families or frequent entertainers.
In real use, these cutters handled raw sweet potatoes with confidence, though slightly more pressure was needed compared to premium models. The lightweight yet durable build makes them easy to control, and the crinkle depth adds excellent surface area for seasoning and browning. They also doubled well on cucumbers and carrots, with minimal snagging. While the wooden handles aren’t dishwasher-safe, they clean up easily with a quick rinse and dry. Storage is simple thanks to their compact size, though a protective sleeve would’ve been a welcome addition.
Against the VITUER or HIA models, this set offers twice the utility for a minimal per-unit cost, though it lacks flashy colors or modern materials.

ADVANTAGES
LIMITATIONS

Don’t let the playful design fool you—its 430 stainless steel blade is sharp enough to slice through sweet potatoes with minimal resistance, producing attractive wavy cuts that enhance both appearance and texture. The PP plastic handle is lightweight and comfortable, while the built-in hanging hole makes storage simple. For casual cooks or beginners, it’s a fun, functional entry point into decorative cutting.
In real-world tests, it handled standard sweet potato prep well, though repeated use on harder roots required occasional repositioning for clean cuts. The 5mm-deep wave design increases surface area for crispiness, making it great for homemade fries. It also worked reliably on apples, carrots, and cucumbers, with easy cleanup afterward. While the plastic feels less premium than wood or rubber, it holds up to regular use. Just avoid twisting motions, as the blade-to-handle joint isn’t reinforced for heavy torque.
Against the Trasylph or HIA models, it lacks extra features like onion holders or rubber grips, but it delivers core functionality at the lowest price. It’s not built for heavy-duty kitchens, but for occasional use or small households, it’s a smart, affordable way to elevate food presentation.

How to Choose the Best Crinkle Cut Knife for Sweet Potatoes
When selecting the best crinkle cut knife for slicing sweet potatoes, focus on a few key features that impact performance, comfort, and durability. Sweet potatoes are denser than regular potatoes, so the right tool makes a big difference in ease of use and results.
Blade Material and Sharpness
Look for high-quality stainless steel blades (like 430 or higher grade). These resist rust, maintain sharpness, and cut through dense sweet potatoes effortlessly. A sharp, deep-ridged wavy blade ensures clean, uniform crinkle cuts without crushing or tearing, which helps with even cooking and attractive presentation.
Handle Comfort and Grip
Since cutting multiple sweet potatoes can strain your hand, an ergonomic, non-slip handle is essential. Materials like rubber, soft-touch plastic, or smooth wood improve comfort and control. Models with contoured or cushioned grips (like the VITUER or HIA) reduce hand fatigue and prevent slipping, especially when hands get wet or oily.
Durability and Build Quality
A solid, one-piece construction (blade and handle fused securely) ensures longevity. Cheaper knives may have weak joints or thin blades that bend over time. Stainless steel blades paired with sturdy handles offer better resistance to wear and frequent use.
Ease of Cleaning and Storage
Choose a knife that’s dishwasher-safe or easy to hand-wash, as sweet potato residue can stick in the blade’s grooves. Some models come with protective covers (like the 2 Pcs Crinkle Cutter Yellow), which are great for safe storage and portability.
Additional Features
- Onion holder included (like Trasylph): Keeps hands clean and safe when slicing strong-smelling veggies.
- Compact size: Fits easily in drawers or knife blocks.
- Multipurpose use: Can cut fruits, cucumbers, carrots, and even soap—great for kitchen versatility.
Prioritize sharp stainless steel blades and comfortable handles for the best experience cutting sweet potatoes. Whether you want premium build, budget value, or family-friendly fun, there’s a crinkle cut knife that fits your kitchen needs.
