The identity of the collection rests on a deliberate dialogue between two materials, kept visible rather than resolved away. Every piece is made from just 5mm aluminum and solid oak.
The PlaneAluminum
Sanded aluminum sheet, waxed for a natural finish in a muted, desaturated slate blue-gray. Sharp architectural lines, geometric rigidity, thin profiles.
The GrainOak
Rich, warm oak. Organic permanence, texture, and the structural mass that grounds each piece.
Precision mechanical joinery
Toolless assembly
Aluminum panels slip directly through precision-milled slots in the oak. No tools required.
No adhesives
Structural rigidity comes purely from geometry, friction, and gravity: no screws, fasteners, or wood glue.
Honest construction
Metal tabs stay visible where they punctuate the wood, turning the logic of the joint into a decorative, functional feature.

Flat-pack & circular
Flat
Ships fully knocked-down, maximizing shipping volume and minimizing transport emissions.
Clean
No permanent glue or fused materials. Aluminum and oak separate cleanly for recycling or repurposing.
Surface
Both materials are sanded to a low grit and finished with wax, so the aluminum ages and matures naturally alongside the oak.

Ombrina
mentored by Ron Gilad
A bedside lamp inspired by paper lanterns, designed as both an ambient and a reading light.
An adjustable mechanical dimmer lets users tailor the light to their needs, from ambient glow to reading.

MWT
Modular Woodturning Tool
A system designed to fit a wide range of existing chisels.
Custom inserts fit an SDS mechanism, securely hold each chisel, and allow quick, easy swapping between tools.
MWT – Woodturning tool systemMockups
2nd Year || Studio B, Part A || Eran Lederman
Throughout the development process, I focused on identifying a unique innovation for woodturning handles with the Japanese saw and the harpoon in mind.
After iterating on various geometries, textures, and ergonomic ‘rhythms,’ I developed a rounded hexagonal profile with a slight offset angle at the end.

This design significantly improves tool angle retention and provides superior leverage during turning.

2nd Year || Studio B, Part A || Eran Lederman
Made for quick and secure tool changes, and a cheaper (pay for the chisel only), more organized woodturning system.
2nd Year || Watches: Time object || Itay Noy
Restless
mentored by Itay Noy
Designed as a recovery-management tool, this watch tracks daily activity to help prevent overexertion following a knee injury.
It marks a technical milestone for Bezalel as the first project to successfully implement CNC milling and turning of Grade 5 titanium.
Restless – Watch designComponents
2nd Year || Watches: Time object || Itay Noy
Engineered to 0.01mm tolerances, featuring a modified Miyota 9100, custom cut and laser etched glass and a 0.2mm heat-patinated dial
Time is presented with minutes in the center and the 24-hour display in the “seconds” position, to further distance time perception from reality.
The result is an automatic watch that visualizes physical activity through its power reserve indicator, serving as a unique productivity tool.

Skipping Grasshopper
Woodturning
Inspired by rock skipping in northern Italy and wanting to challenge my craft-ability, I used randomized Sinc functions in Grasshopper to generate ripple patterns and laser-cut tool profiles for precision woodturning.

simply a tool
mentored by Nitsan Debbi
Head of Bezalel’s Industrial Design department and senior designer at Naoto Fukasawa
A course that uses “simple” design thinking and rapid development to create multiple tools, then a whole system out of one of them.
The year I took part, the focus was cutlery, and I was ranked best in class.
“simply a tool” – Set
3rd Year || “simply a tool” || Nitsan Debbi
Driven by the ‘finger method’ for measuring soup thickness and the lollipop “icon,” this series uses a revolved cut to define its functional identity. This geometry creates a tactile, shallow bowl for the spoon and a sharp edge for the fork and knife, resulting in a durable, CNC-machined maple set and stainless steel spoon.
“simply a tool” – Dosage
3rd Year || “simply a tool” || Nitsan Debbi
Responding to a measuring spoon brief, I utilized brass for its antibacterial properties to create a specialized tool for health supplement and pill dosages.
The final outcome features two distinct sizes: a compact version for a single dosage, shown here with an Advil, and an elongated model tailored for a double measurement, scaled to standard supplement dimensions.
“simply a tool” – Charred quenelle
3rd Year || “simply a tool” || Nitsan Debbi
A bite inspired by Chef Giuseppe Gasperoni Based on a brief interview and further research, we were tasked with creating a spoon for Milan Design Week that reflects Chef Gasperoni’s unique philosophy, combining tradition with contemporary innovation. January 2025
Crafted from maple scrap wood sourced from sap-harvested trees, this gelato spoon is designed to be gently charred in front of guests, imparting a delicate burnt aroma and flavor. The warm material and quenelle shape enhance the gelato experience.
A group project in Collaborative Design Processes, the first course of my master’s. Our theme, set by the Danish Plastics Federation, is design for disassembly, and we chose the ZinCo Georaster green roof element as our case.
The course follows the Double Diamond, from Discover through Deliver.

Plastic Data Mapping
Nordhavn route 12 September 2026
An interactive map of the plastic found along a walking route through Nordhavn, Copenhagen. 51 artifacts were documented across four sites in 39 entries, each photographed and logged by material, colour, wear, texture, and whether it’s reusable or disposable.
Walk the route site by site, spin the wheel for a random find, or regroup the whole collection in Selma’s Sort.

About
I am Koren,I mix a crafty, hands-on approach, 3D modeling, deep research and user-centered thinking to solve real-world problems. With a background in Agile tech teams, I connect design and engineering and keep projects moving smoothly across disciplines.
I’m now pursuing an MSc in Strategic Design & Entrepreneurship, a joint program of the Royal Danish Academy and Copenhagen Business School, and I’m especially interested in the consulting world, where design, strategy and business meet.
