Most knife blocks look like a small wooden office building where your cutlery goes to avoid eye contact. This blue resin magnetic knife block gives every blade a window seat. SENKEN’s Tsunami turns a practical place to park your kitchen knives into something that looks like a satellite photograph of an extremely fancy coastline.

The actual object is refreshingly straightforward: a wide, upright panel made from natural burl wood and blue resin, supported by two beech hardwood bases. Hidden magnets hold compatible steel knives against its faces. You can see the blades, pick the one you want, and put it back without trying to remember which mysterious slot belongs to the bread knife.
It is knife storage with a considerable interest in interior decorating. The wood supplies warm grain and irregular edges; the blue resin fills the spaces around it with color. Together, they make an ordinary collection of chopping tools look like it has been invited to a gallery opening. Your onion is still going to make you cry, but at least the scenery has improved.
A magnetic knife block with two useful sides
The Tsunami is double-sided, with multiple rows of concealed neodymium magnets. SENKEN rates its capacity at up to 16 kitchen knives across the two faces. That is an upper limit, rather than a promise that any 16 blades you own will fit comfortably. A broad cleaver takes up more room than a small paring knife, and handles need enough space for you to grab them.
The practical appeal is the absence of dedicated slots. Instead of a block deciding where your chef’s knife is allowed to live, you arrange compatible knives across the flat surface. SENKEN lists chef’s knives, santoku knives, bread knives, cleavers, and paring knives among the shapes it can accommodate. Magnetic steel kitchen shears and similar tools can also join the lineup.
That compatibility detail matters. The magnets need a blade or tool they can attract. A ceramic knife is not going to become cooperative just because the backdrop is beautiful. Think of this as storage for suitable magnetic steel utensils, rather than a universal parking permit for everything in the kitchen drawer.

Measure the counter before adopting the coastline
This is the extra-large model, and it earns that description through width. The manufacturer lists the panel at 15.75 inches wide, 9.75 inches high, and 0.75 inches deep. Those are the block dimensions, not a guarantee that its entire working footprint is only three-quarters of an inch deep. The two bases project outward, and knives occupy space on both faces.
In other words, give it a real place on the counter. If you tuck it tight against a backsplash, the rear storage will be harder to use. Leave space to reach the handles without knocking neighboring utensils together. A double-sided block makes the most sense where both sides can actually do their jobs, instead of one becoming the kitchen equivalent of a blocked emergency exit.
SENKEN lists the block itself at approximately six pounds, or 2.75 kilograms, without the bases. The two hardwood supports help it stand upright. It is a substantial display piece, not a folding organizer that vanishes into a drawer when company arrives. For someone with a little counter space and a lot of affection for their knives, that can be the point.
| Detail | What to expect |
|---|---|
| Panel materials | Blue resin and natural burl wood |
| Supports | Two beech hardwood bases |
| Panel dimensions | 15.75 inches wide × 9.75 inches high × 0.75 inches deep |
| Listed panel weight | About 6 pounds, without bases |
| Storage | Both faces; up to 16 compatible knives |
| Included knives | None; knives are sold separately |
The most useful way to plan your arrangement is to start with the knives you reach for regularly. A few comfortably spaced tools are easier to choose from than a perfectly packed wall of overlapping handles. You do not have to fill every available inch simply because the product description has given you a number to beat.
- Put frequently used knives where their handles are easy to reach.
- Allow extra room for wide blades and bulky handles.
- Keep access to the back face clear if you intend to use both sides.
- Check that each blade is magnetically compatible before relying on the holder.
- Remember that the display photographs include separately sold knives.

The wood grain does the decorating
The blue is the first thing you notice, but the burl wood keeps the design interesting after that first glance. Grain swirls across the face in uneven shapes, with the resin following the natural boundaries. It resembles a little abstract landscape without requiring you to explain what the artist was feeling. Apparently, the artist was feeling that the knives needed somewhere to stand.
Because the wood is natural, SENKEN says the grain patterns vary from piece to piece. Expect the same general blue-and-wood combination rather than a precise copy of the photographed pattern. That is part of the appeal if you like natural materials, and something to remember if you are trying to match one exact swirl to your kitchen wallpaper.
The shape is a clean rectangle. Despite the Tsunami name, there is no curling wave sticking out of the top or aquatic sculpture consuming your prep area. The drama comes from the color and grain inside that simple outline. It is bold enough to be noticed, but the basic layout still reads as a useful kitchen organizer.
Matching blue resin handles make a particularly coordinated display in SENKEN’s photos. They are optional styling, not a requirement for using the block. Suitable knives you already own can provide the practical part. This purchase is the holder itself; it does not quietly include an entire knife collection just because the photographs look very well equipped.

Open storage has a few everyday tradeoffs
Being able to see the blades is convenient, especially if several of your knives have similar handles. You can identify the serrated bread knife immediately rather than performing the usual slow reveal from a wooden slot. The exposed faces also mean there are no individual knife slots to reach into when wiping down the holder.
Open storage does leave the blades visible and accessible. Position the block thoughtfully, away from an edge where it could be bumped and away from children. It is a display holder, not an enclosed or locking cabinet. The attractive blue surface does not change the fact that its daily job is holding sharp kitchen tools.
Care is simple but not optional: SENKEN specifies wiping it with a damp cloth and drying it thoroughly. Do not soak it. That is a manageable routine for a countertop object, and also an excellent excuse to avoid treating every kitchen item as though it belongs at the bottom of a sink full of pasta water.
For a cook who enjoys choosing tools and keeping them visible, the Tsunami offers a distinctive alternative to a slotted block. For someone whose goal is to have absolutely nothing on the counter, a wide display panel probably will not win the argument. It knows what it is, and subtle disappearing act is not on the menu.
