Some observations from a Swedish scyther on ground vs. peened blades that largely mirrors my own. Lie = scythe, egg = edge, orv = snath, knocked = peened, and I think you can understand the rest without issue but if any of the untranslated words cause a stumbling block just ask and I probably have a reasonable idea of what they mean thanks to all the wading through Swedish scythe pages at this point. :p
From Google Translate (emphasis added):
As far as I know, there is currently no good answer to why Sweden has become the ground liens promised land. Sweden is certainly not alone in having a strong tying the grindstone, but hardly in any country is the tradition so dominant.
Neighboring Norway, this is also the sharpened scythe of dominance but the technology to cold-hammering or knocking out one egg has a larger spread in general. This technology has its own verb, tynsling, which I was taught by a knife craftsmen.
Now the interest knack scythes to grow in Sweden. Hopefully it will lead to the user of the sharpened scythe receive part of the inspiration that characterizes many of these new practitioners of the knocked lien. For there is in my experience a lot to learn from lieentusiaster around our world in terms of both equipment and technology. Lessons will be for the benefit of present and future users of the sharpened scythe.
When studying users of the sharpened scythe is evident that the greater extent than users of the knocked lien uses speed to master a given mowing situation. Users of the sharpened scythe can often be seen with a shorter and rapper sweep of the scythe. This technology also fits in to the fact that we in Sweden have traditionally used the shorter orv. This does not apply to all places in our country, but with the factory-made red plåtorvet reinforced this pattern.
At one of my demonstrations, a woman came forward and explained that my equipment was too "heavy". Much thanks to this "lesson" she wants to convey, I have systematically tried to learn the peculiarities of the Swedish lietraditionen that led to the conclusions I am here trying to convey.
The short rapid blows could in some circumstances be only one league goal - the stony and very hilly notch hit - but as a general technique to manage the lien is more questionable. In particular, to speed costs more energy than it increases the removal rate. The solution to this problem is in my experience to become sharper at handling sharpness. That favor sharpness before speed.
There is further a feature where the Swedish lie different from the continental knocked lie. The Swedish sharpened scythe is straighter and straighter seen in the horizontal plane. It's all about the line liens egg is then placed on the ground. The blade tip is then as close to the ground as lieeggens beginning at the clamp. Liebladet is thus almost straight. Do you have any old liar of Swedish production, this is easy to state. Liefabrikanterna Hamre in Norway and Härmän in Finland is working to produce these straight liar.
The scythes produced for the Swedish market of lietillverkare as "Fux" from Austria, by contrast, gave those of them bought Ljungdahlsliarna a more continental design. It's about the warp which lien has been in the blade length direction, and allows liens tip pointing slightly upwards. There is an advantage of this curvature, looking liebladet not as light soil, that the tip does not stick easily to the ground. But a straight lie also has an advantage in that the line or the plane of the edge cutting line images during its movement through the crop is thinner which leads to leibladet cutting better, it feels like it is sharper.
But for this advantage really to fall out of the driver must lie to have a good control of liens "forgotten angle". It is the angle increases as the lien held against the ground and liens tip turned up while pliers end remains on the ground. Most liar need not adjust the angle. It is determined by the tangent direction transverse to coincide, in line with, liebladets length.
