Refurbishing a cuttingboard - the frequenty asked quastions about our Hygienic-Scraper

Hello,
I'm Michael from Schneidbrettguru and this video is about the most common questions or concerns about the hygiene scraper. There are 7 pieces in total - so let's get started:
One of the most common questions is " Can I somehow break the hygiene scraper, because that's just such a thin sheet of metal".
What you should know first: The part is made of spring steel (you'll see the "why" in a moment). It only cuts because a cutting burr has been pressed onto the longitudinal edges through targeted deformation. It protrudes into the surface here. This is noticeable and audible when I go over the edge here.
For use, this means that I have to move the part over the surface, standing on the edge and inclined in the direction of the burr, so that something is removed. So not like scraping with a spatula (I've seen the wildest things there), but inclined in about 5-10 degrees in the machining direction.
Speaking of machining direction: There are only 2 possibilities: pull or push. Since, in principle, the cutting burr remains stuck in the surface, it is similar to going over the field with a plow.
Now pulling has the big disadvantage that due to the inclination I can only absorb the complete resistance by squeezing my fingers together; otherwise I slide away upwards.This is quite sporty to hold and is thus more suitable as finger strength training for climbers.
Pulling is not wrong in principle - but it only makes sense, for example, with very narrow workpieces. Then I can put my fingers sideways and see what I'm doing.The other is when I want to smooth a wooden surface only very delicately - i.e. only apply a little force.But to free a cutting board from cut marks, this is definitely too strenuous, because we are removing a relatively large amount of material.
So the motto here is: if you love your cutting board, you push it.This is much easier if you do it right. Pushing alone is not the solution, but the big secret is to use as little force as possible.
How do you do that?Quite simply, by having as little resistance as possible.This, for example, is a cutting board plane. These things go super heavy in proportion because they have a fixed blade width of (in this case) 6 cm.
One advantage of the hygiene scraper is that the part (as mentioned at the beginning) is made of spring steel. This allows me to bend it relatively easily and thus - when I push it at an angle over the surface - reduce the cutting width. Then I have only 2 cm instead of 6 cm.Depending on where I bend it or hold my thumbs, which form the center point, I can move these 2 cm along the entire edge length and thus take advantage of everything.
However, we must now first make sure that the board is fixed.For this I recommend such an anti-slip mat for cabinets...gibts for around 2€ in remnant stores. If that is not enough, place the board against a stop in the direction of machining.This can also be the wall at the worktop.
To save even more force, the scraper is held as far as possible at the bottom of the edge - where the resistance arises. Your fingers can rest on the surface of the board - it doesn't matter, as long as there are no chips sticking out of the wood.There is a relatively simple method for finding the optimum angle:
I take the scraper just so - that is, thumb back, press through slightly, and now I look at a smooth surface to see at what point the cutting burr grips and leaves small cuts.It sounds like it's sticking. Now when I push through against that resistance, it wears material away.
