Tamiya Craft Tool Series No.98 Modeler's Knife PRO 74098 Review (2026)

What is included in the kit

The Modeler's Knife PRO ships with seven blades in three different profiles, made up of three straight blades, two curved blades and two flat blades, giving a builder several cutting geometries without needing separate knives for each one. A protective cap is included for safe storage between uses, and Tamiya sells a separate plastic case sized for the replacement blades once the included set wears down. This is a Japan-manufactured tool, consistent with the rest of Tamiya's Craft Tool Series line of modeling accessories, which are designed to complement Tamiya's plastic model kits.

Grip, blade mounting and build quality

The handle body uses an elastomer resin grip, which Tamiya describes as giving a non-slip, comfortable hold during longer cutting sessions, an advantage over the smooth plastic handles found on many budget hobby knives. Blades are held in place with a metal chuck mechanism rather than a simple friction fit, which is meant to keep the blade from shifting or working loose mid-cut, particularly useful when applying steady pressure to trim sprue gates or clean up resin parts. Because Tamiya builds this specifically for its Craft Tool line, the fit and finish is consistent with the rest of that tool series, which modelers generally regard as durable for years of bench use.

Curved and flat blades versus a standard straight blade

The inclusion of curved and flat blades alongside the standard straight ones is the main functional difference from a typical single-profile hobby knife. Curved blades are useful for slicing along rounded surfaces or scraping mold lines without digging into the plastic, while flat blades can get into tight recesses that a pointed straight blade cannot reach cleanly. This variety makes the knife more versatile for detailed scale modeling tasks like canopy masking prep or panel cleanup than a knife that only accepts one blade shape, though it also means a builder needs to learn which blade suits which task.

Cost of ownership over time

Because this is a Tamiya-specific tool, replacement blades for the straight, curved and flat profiles are sold under Tamiya's own part numbers rather than being interchangeable with generic X-ACTO or Excel style blades. Tamiya's own blades tend to carry a higher price than generic equivalents, so builders who go through blades quickly on high-volume projects will pay more over time to keep this knife sharp compared with a knife that accepts widely available third-party blades. That cost is offset somewhat by the knife's durability and the precision Tamiya blades are known for, which can mean fewer blade changes for the same amount of cutting. Buying a full spare set of all three blade profiles at once, rather than restocking one type at a time, is one way builders manage the ongoing cost without running out mid-project.

Verdict and who it suits

This knife earns a 9 out of 10 for fitting the job and a 9 out of 10 for build and materials in our data, reflecting that it was designed from the ground up for plastic model work rather than adapted from a general craft knife. It is a strong pick for builders who want one dependable, precise cutting tool and do not mind paying more for Tamiya-branded refills. Builders on a tighter budget, or those who already own a supply of generic hobby blades, may get similar day-to-day cutting results from a cheaper knife that uses more widely available blade types.
