Is a 300mm depth Parker Asahi Pro cutting board sufficient for a 240mm Gyuto?

This site has not compared the Parker Asahi Pro cutting board, and none of the picks in our cutting board guide publishes a 300mm depth, so the question cannot be answered from published figures here. The same applies to the 240mm Gyuto: no pick in that guide publishes a blade length, so there is no cited figure to set against a board depth.

What follows is a scope note, not a verdict. A board depth and a blade length are different measurements, and a maker who publishes one does not automatically publish the other. The sections below set out what the picks in Best Cutting Boards for Plastic and Titanium Sets do publish, and where the published record stops.

What the cutting board guide actually publishes

The guide compares five picks, and each one publishes its size in inches. The THETCHRY set lists a large board at 15 by 10 in, a medium at 11 by 8 in and a small at 9 by 6 in. The GORILLA GRIP set lists a largest board at 16 by 11.2 in, a medium at 13.8 by 9.6 in and a small at 11.8 by 8 in, each .37 in thick.

The Empune set publishes an extra large board at 17.0 by 11.8 by 0.4 in, a large at 14.0 by 9.5 by 0.35 in and a medium at 11.4 by 7.8 by 0.35 in. The Sumzzz board is listed at 16 by 11 in, and the Pexucalm board at 15.4 by 10.4 in. Every one of those figures is in inches, and none of them is a 300mm depth.

That matters for the question. A 300mm depth is a metric figure, and no pick in the guide publishes a depth in millimeters or in any metric unit. The guide’s picks publish their sizes in inches only, so there is no cited board on this site whose depth can be matched to a 300mm figure without converting, and this site does not convert.

Depth and length are not the same measurement

Cutting board listings usually give two footprint figures, and the order is not always consistent between makers. The THETCHRY set describes its large board as 15 by 10 in, and its feature text calls that the length by width. The Empune set publishes 17.0 by 11.8 by 0.4 in for its extra large board, with the third figure as thickness.

The Sumzzz board is titled 16 by 11 in, and its fact sheet block lists a width of 10.79 in and a depth of 15.55 in, which do not match the title figure exactly. The Pexucalm board is titled 15.4 by 10.4 in, and its block lists a width of 10.4 in and a depth of 15.4 in. In both cases the larger figure is recorded as depth.

So a depth figure on this site means the longer footprint edge as the fact sheet records it, not a front to back working depth behind a blade. A 300mm depth, if a maker published one, would need to be read against that same convention before any comparison to a blade length made sense. No pick here publishes such a figure.

No pick publishes a Gyuto blade length

The question pairs a board depth with a 240mm Gyuto blade. None of the five picks in the cutting board guide is a knife, and none publishes a blade length, a blade height or a knife dimension of any kind. The guide compares cutting boards, so the published record covers board footprints, thickness and weight, not knives.

Several picks do describe knife contact in general terms. The Pexucalm listing states that its wheat straw PP side is a softer material that protects knife edges from rolling. The Sumzzz listing states that its titanium surface is smooth and durable and less likely to retain residue than some traditional materials. Neither statement includes a blade length or a board depth figure.

Without a published blade length for the Gyuto, there is nothing on the fact sheet to subtract from a board depth, and this site does not derive differences. The honest answer is that the fit of a 240mm blade to any board in the guide has not been compared here, because the guide publishes no knife figures at all.

Published thickness and weight across the picks

Thickness is published for several picks. The GORILLA GRIP set lists each board at .37 in thick. The Empune set lists 0.4 in for the extra large board and 0.35 in for the large and medium boards. The Pexucalm board lists a height of 0.5 in, and the Sumzzz board lists 0.94 in.

Weight is published unevenly. The THETCHRY block lists 1.4 lb, while its feature text states the board weighs 2.3 pounds. The GORILLA GRIP block lists 4.24 lb, and its feature text states a combined 4.25 lbs for the set. The Empune block lists 4.53 lb. The Sumzzz and Pexucalm blocks list no weight.

None of those figures speaks to blade clearance. Thickness tells you how far the cutting surface sits above the counter, and weight tells you how much the board carries, but neither is a statement about how much room a long blade has on the surface. The guide publishes no figure that addresses that question for any pick.

How to read the absence of a figure

When a maker does not publish a figure, this site says so rather than filling the gap. For the Parker Asahi Pro board, this site has not compared it, so no figure from that maker appears here at all. For the five picks in the guide, the published sizes stop at the footprint and thickness figures listed above.

A reader weighing a 300mm board against a 240mm blade can still use the published record for what it covers. The largest footprint in the guide is the Empune extra large board at 17.0 by 11.8 in, and the smallest is the THETCHRY small board at 9 by 6 in. Those are the outer bounds of what the guide documents.

Anything beyond that, including whether a 300mm depth leaves enough room behind a 240mm Gyuto, sits outside the published figures on this site. The useful next step is to read the maker’s own listing for the Parker Asahi Pro board and for the knife, since those are the only places a 300mm depth and a 240mm blade length would be stated in the units their makers chose.
