In Japan originally no grip recesses were mortised, but the Shoji were handled at the frame and pushed, then a field was pasted on the back in such a way that it could then be used for grasping (see picture). We still find this way of ensuring operability in the sliding doors of the tea rooms today.
For a long time now, it has become usual to use hikites made of precious woods in the coniferous wood frames of the Shoji in order to achieve, among other things, an upgrading. Therefore, you can still find handles made of rosewood, ebony, rosewood but also cherry.
But there is another possibility: the grip recesses are milled directly into the frame woods of the Shoji.
Now I don't only offer the hikites made in Japan, but I have always made these recesses out of the residual woods that are used in my workshop for the construction of individual pieces. In the offer you find at the moment handles e.g. from sycamore maple, steamed pointed maple, beech, walnut.
