The Ergonomic Scan
Custom handle shape recommendations based on grip style and hand kinematics
Grip Style Analysis
Select your primary grip style to receive handle shape recommendations. Our system analyzes hand kinematics and pressure distribution patterns to suggest optimal handle geometries for your cutting technique.
Each grip style corresponds to specific handle shapes: Wa-style for precision work, Western for power cutting, and Octagonal for versatile applications.
Select Your Grip Style
Pinch Grip
Precise control with fingertip pressure distribution. Ideal for detailed cutting work requiring fine motor control.
Power Grip
Maximum force transfer for heavy cutting tasks. Optimized for extended use with minimal fatigue.
Precision Grip
Balanced control for versatile cutting techniques. Combines accuracy with comfort for general kitchen work.
Hybrid Grip
Switching between multiple grip styles during use. Designed for multi-purpose kitchen applications.
Handle Shape Specifications
Wa-Style Handle
Oval cross-section with tapered profile. Designed for pinch grip with optimal finger placement and pressure distribution. Length typically 120-140mm for standard kitchen knives.
Western Handle
Full-tang design with ergonomic palm swell. Optimized for power grip with enhanced force transfer. Comfortable for extended cutting sessions requiring sustained pressure.
Octagonal Handle
Eight-sided cross-section providing multiple grip reference points. Versatile design supporting various grip styles. Suitable for tasks requiring grip transitions during use.
Hand Kinematics Analysis
Pressure Distribution
Different grip styles create distinct pressure patterns across the hand. Handle shapes are designed to distribute force evenly and reduce pressure points that can cause fatigue during extended use.
Analysis considers thumb placement, finger curl radius, and palm contact area to determine optimal handle dimensions and contour profiles.
Range of Motion
Handle geometry affects wrist angle and arm movement during cutting tasks. Ergonomic designs minimize awkward postures and reduce strain on joints and muscles.
Measurements include wrist flexion, radial deviation, and forearm rotation to ensure comfortable cutting motion throughout the working range.
Customization Options
Length Adjustment
Handle length can be modified to match hand size and cutting technique preferences. Standard measurements range from 100mm to 150mm.
Contour Profiles
Cross-section shape affects grip feel and comfort. Options include variations in width, depth, and edge radius to match individual preferences.
Surface Texture
Finish options range from smooth polished surfaces to textured grips. Selection depends on moisture conditions and desired tactile feedback.
Weight Balance
Handle material and dimensions contribute to overall tool balance. Adjustments can shift center of gravity to match cutting style preferences.
