The shapers that KGE are using is custom made according to KGE’s own measurements. KGE oboe reeds are made from type “B” and “D” shaper: “Original”: shaped as dry, “Narrow”: shaped as been soaked in water. “B” shaper plays better intonation with large bore Oboe like Loree, Howarth, Rigoutat etc. “D” shaper plays better intonation with smaller bore oboe like Marigaux, Josef, Ludwig Frank, K.GE etc.
The only difference between the “German” and “French” templates is that there is a much more gradual step in the scrape from the “heart” of the reed down to the tip on the french template. When you look carefully at reeds made from each of the two templates and compare them, it will look as if the german template reed has a much more clearly defined tip area.
Both the “german” and “french” scrapes would work on all oboes.
