MAC Knife Professional 8-Inch Hollow Edge Chef Knife: Full Review

The MAC Knife Professional 8-inch hollow edge chef's knife (model MTH-80) is one of the most recommended chef's knives in professional kitchen circles. If you've been researching chef's knives seriously, you've encountered it. This article explains exactly what makes it stand out, what to expect in real use, and whether it's the right choice for your cooking style.

The MTH-80 is not cheap. At roughly $160 to $180 at most retailers, it sits in the upper mid-range of kitchen knives. The question worth answering is whether what it offers justifies that price.

What the MTH-80 Actually Is

MAC Knife is a Japanese company founded in Seki City, Japan in 1964. Seki is the center of Japanese knife manufacturing, home to dozens of cutlery brands. MAC's Professional series occupies a specific niche: Japanese blade geometry and steel quality at a price point lower than Shun or Global, with enough robustness for the demands of professional kitchen use.

The MTH-80 is named for its features: M = MAC Professional, T = tapered spine, H = hollow edge (Granton edge).

Steel

The MTH-80 uses MAC's proprietary steel, which they describe as high-carbon, high-molybdenum stainless. The hardness is approximately 58 to 59 HRC, which is harder than most German knives (typically 56 to 58 HRC) but softer than hard Japanese knives like Shun (60 to 61 HRC) or MAC's own Japanese series.

At 58 to 59 HRC, the steel holds an edge well, needing serious sharpening perhaps twice a year with regular home use. It's hard enough to take an acute edge but not so brittle that it chips easily from normal kitchen use. This balance between hardness and toughness is one of the things that makes the MTH-80 work for both home cooks and professionals.

Blade Geometry

This is where the MTH-80 distinguishes itself from most Western chef's knives.

Spine thickness: The spine is 2.5mm at the heel, tapering to 1mm toward the tip. German knives like Wusthof Classic are typically 2.0 to 2.5mm throughout, meaning they taper much less. The dramatic taper on the MTH-80 means the blade feels progressively lighter and more precise as you work toward the tip.

Grind: The blade is ground thin behind the edge, which reduces the resistance you feel when the knife passes through food. When you're slicing a carrot or an onion, you feel less of the food "gripping" the blade as it moves through.

Hollow edge (Granton): The MTH-80 has oval dimples ground into both sides of the blade above the edge. These create small air pockets that reduce the adhesion between the blade and the food being cut. Sticky foods like potatoes, cooked beets, and soft cheese are less likely to grip the blade. Whether you notice this effect depends on what you're cutting, but it's a real functional benefit for certain tasks.

Edge angle: The factory bevel is 15 degrees per side, which is finer than the 20 degrees per side of most German knives. A 15-degree angle produces a sharper cutting edge but is slightly more delicate, meaning it needs care on hard foods like frozen items or heavy bones.

Handle Design

The handle is black polypropylene, slightly softer than the handles on fully traditional Japanese knives, and it has a comfortable contour for a pinch grip. Western-trained cooks who grip near the blade with thumb and forefinger on the blade itself find it comfortable. The handle has a small bevel at the bottom that serves as a finger guard.

Weight-wise, the MTH-80 is about 6.5 ounces. That's lighter than most German chef's knives (Wusthof Classic is about 8 ounces for the same blade length) and in the middle range for Japanese knives.

How It Performs in Daily Use

The MTH-80 cuts with noticeably less effort than a German-style chef's knife. The thinner grind, harder steel, and acute edge angle all contribute to a blade that moves through food more cleanly.

Vegetable Work

This is where the MTH-80 is particularly strong. Fine julienne cuts, paper-thin slices of ginger, precise herb mincing: the thin blade and sharp edge make this work feel effortless compared to a heavier German knife. Onions, bell peppers, carrots, and leafy greens are quick work.

The Granton edge helps with sticky vegetables. Sliced potatoes and cooked beets come off the blade cleanly rather than adhering.

Protein Work

Slicing boneless chicken breasts, trimming flank steak, portioning fish fillets: the MTH-80 handles these cleanly. For bone work, be careful. The 15-degree edge angle is not designed for chopping through bone. Use a cleaver or a heavier knife for that.

Bread and Crusty Foods

The straight edge (not serrated) handles soft bread adequately but a serrated bread knife is still preferable for crusty artisan loaves. For sandwiches and soft rolls, the MTH-80 is fine.

MTH-80 vs. Competitors

At the $160 to $180 price point, several serious chef's knives compete for the same buyer.

MAC MTH-80 vs. Wusthof Classic 8-inch

The Wusthof Classic runs about $150 to $180. It has softer steel (58 HRC), a heavier blade, and more durability for rough tasks. The German-style geometry and heavier weight make it more forgiving if you're not precise with maintenance. The MAC is sharper and more precise but less suitable for abuse.

Which is better depends on your style. Precision cooks who care about minimizing effort in cutting will prefer the MAC. Cooks who want a durable all-purpose blade that tolerates occasional rough handling will prefer the Wusthof.

MAC MTH-80 vs. Shun Classic 8-inch

Shun Classic runs $140 to $170. It uses VG-MAX steel at 60 to 61 HRC, making it harder than the MAC and therefore both sharper-capable and more chip-prone. Shun's Damascus cladding looks striking. Performance-wise, both are excellent; the Shun needs a little more care on harder foods.

MAC MTH-80 vs. Global G-2 8-inch

Global's G-2 runs $120 to $150. All-stainless construction (including the hollow handle), lighter weight, and similar Japanese-origin precision. The MAC has better steel hardness and thinner geometry. For home cooks, both work beautifully, but the MAC's handle is more comfortable for a wider range of grip styles.

Maintenance Requirements

Sharpening

At 58 to 59 HRC, the MTH-80 benefits from whetstones over pull-through sharpeners. The acute edge angle needs to be maintained accurately for the knife to perform as designed. A 1000-grit stone followed by a 3000 to 4000-grit stone is a good maintenance sharpening. For a full re-edge after a long period of use, start with 400 to 600 grit.

The Granton dimples don't affect sharpening on a whetstone because you're only working the edge bevel, not the sides of the blade.

Honing

Use a smooth ceramic honing rod rather than a ridged steel rod. The harder steel responds better to smooth ceramic, and the ridges on a standard steel can be aggressive for a 58 to 59 HRC blade.

Cutting Surface

Always use wood or plastic. Avoid glass, ceramic, marble, or any material harder than the steel. At 58 HRC, edge chipping on hard surfaces is a real risk.

Storage

Magnetic strip, knife block, or blade guard. Don't store loose in a drawer where the edge contacts other objects.

Who Should Buy the MTH-80

The MAC MTH-80 is the right knife for:

• Home cooks who do significant daily prep and want a blade that makes the work feel easier
• Anyone familiar with Japanese knives who wants proven reliability at a sub-$200 price
• Cooks who sharpen their knives or are willing to learn
• Professionals who want a reliable daily driver that doesn't require a second mortgage

It's less ideal for: - Cooks who want to put knives in the dishwasher or handle them roughly - Anyone not interested in maintenance - Cooks who primarily do heavy work like splitting bones or cutting frozen food

FAQ

What does the hollow edge (Granton edge) actually do? The dimples create small air pockets that reduce suction between the blade and food. Sticky foods like soft cheeses, cooked potatoes, and cucumber slices release from the blade more easily. It's a real effect, though modest, not a dramatic transformation.

Is the MTH-80 a good first Japanese knife? Yes. It's more forgiving than harder Japanese knives while still demonstrating the geometry and cutting feel that distinguishes Japanese blades. It's often recommended as a gateway Japanese knife for cooks coming from German knives.

How does the MTH-80 compare to MAC's other lines? MAC also makes the Superior series (softer steel, lower price), the Chef series (similar to Professional but different geometry), and the Japanese series (harder steel, thinner grind, more demanding maintenance). The Professional MTH-80 is the sweet spot for most buyers.

What is the best way to store the MTH-80? A magnetic strip is ideal. The blade is thin and the Granton edge is easier to inspect for chips when the knife is visible. A knife block works too, but avoid loose drawer storage.

Conclusion

The MAC Professional MTH-80 earns its reputation. The combination of Japanese-origin precision, forgiving enough steel for real-world kitchen use, and an ergonomic handle that suits a variety of grip styles makes it one of the most complete chef's knives available at its price point.

If you're spending $150 to $200 on a chef's knife, the MTH-80 belongs on your short list alongside the Wusthof Classic and Shun Classic. It outperforms both in precision cutting tasks and matches them in durability with proper care. Our Best 8 Chef Knife guide has the full comparison if you're still deciding between them.
