We sometimes receive HL5 and W968 blades for repair. I also know some of my friends who have these blades, and I can tell you the handles are different. There are thinner and fuller handles.
I currently have a HL5 blade (H17_79 HL5 BCXAXAF 090) being repaired, with a 5.9 mm blade thickness.
The handle dimensions are:
Length - 100.5 mm
Top - 26 x 23 mm
Middle - 26 x 24 mm
Bottom - 34.8 x 26.4 mm
As you can see from the dimensions, this handle is almost the same as the handle
@vossi39, but a little thicker at the end
Top of handle: 25.8 x 23.0 mm
Middle: 26.6 x 23.3 mm
Bottom: 33.3 x 25mm
Blade number: 23
Previously, I had a W968 blade with an uneven blade thickness of 5.9 mm at the top and 5.5 mm at the chord.
Handle dimensions based on blade photos:
Length - 101.2 mm
Top - no data
Middle - 25.7 x 22.7 mm
Bottom - 34.85 x 25.9 mm
It's likely that this handle is thinner because the blade itself is thinner
Previously I also had for repair another W968 (20240903_1) blade with a thick handle. I didn't measure the handle dimensions, but there's a photo showing the handle itself compared to the handle of my blade.
I'll also take a photo of the HL5 blade I currently have, compared to the same handle.
