我覺得這個設計是又醜又蠢。

首先，幹嘛加這個東西？看看原廠的說明吧。反正就是為了你的安全，是他們的先進的設計．．．

要是你相信的話，你大概也會相信2012就是世界末日。看看原廠的說明吧。

Those who have followed the nearly 25 years that the Sebenza has been around know we continually make small improvements, alterations, advances to our knives. None of these changes are made to follow a trend, to keep up with the Jones or to tick off our customers. They are done to improve performance, safety or production. That we make a change to the Umnumzaan should not come as a surprise.

The disc has been added to the Umnumzaan to prevent the reduction of tension on the lock. Because the shape of the Umnumzaan handle is a little different than that of the Sebenza, it takes a different technique to open and close. We have found some customers are not willing to learn the difference or perhaps they don’t recognize the difference but, whatever the reason, they think it is necessary to modify the lock tension, thinking the knife will open more easily. This simply makes the knife unsafe. We have had several Umnumzaans returned to us because of lock issues – almost always the customer denies having modified the lock. We can see what has been done, and are put between a rock and a hard place as we don’t want to call out the customer for not telling the truth. The disc is a solution to prevent potentially unsafe modifications.

Please note this disc is not a lock stabilizer as it has been called in some posts. It is simply in place to prevent the lock bar from being pushed out to reduce tension. Our locks are fitted properly to very close tolerances and do not need to be stabilized. And to save further speculation, the disc is press fit into the handle. It is made of 303 stainless steel, and is sandblasted along with the rest of the handle. Because it is not titanium, the sandblasted finish looks different.

Will it change further? Quite possibly. What might these changes be? No idea at this time.

It will be a while before you see Umnumzaans other than the Wilson Startac with this disc. This has to do with our on-hand inventory of machined handles.

We are not planning to add the lock override protection disc to the Sebenza. We do not have the issue of lock modification by customers to the same degree as we do with the Umnumzaan.

Before the question is asked here is a quick reminder of the difference in how to open an Umnumzaan and a Sebenza.
Umnumzaan: slide your thumb straight forward, parallel with the handle, pushing the lug with the top center of your thumb.
Sebenza: push the lug out sideways in a sweeping motion with the side of your thumb.

Since there has been renewed discussion about Idaho Made in this thread, you might find it interesting to note that since March this year, the value of our back orders has almost quadrupled. This would indicate there are not too many concerns about the Idaho Made marking.

We appreciate your loyalty and enthusiastic conversation. We know we can't please all of the people all of the time!

但我想的只有一件事，如果真的有錢，我還是會想買一把Umnumzaan，蟲鳴老師不要打我啊！

不敗教主評曰：
自從五百年前，我用不敗教的頂級神功＂大夢如癡＂，將敗家教主＂卡爾缺錢＂，困死在三十九重天＂醉生夢死＂之中。
本以為天下武林已經太平，沒想到敗家教主居然在最後關頭，啟動寫輪眼對我施加催眠大法＂有眼無珠＂，我竟不察覺敗家教主最後一個分身，仍然逍遙法外、荼毒武林。
這也怪我，當初修習不敗神功最後一章＂少時不投資，老大徒傷悲＂，因為有幾句心法一時無法體會，以致神功雖成，卻不完整！
如今經過股海＂傾家蕩產＂的洗禮之後，不敗教主＂一貧如洗＂的神脈已然貫通，神功終於大成，此時已無敵於天下。
我打算用不敗神功最後三大奇招，來對付敗家教主，一舉剷平敗家教！
首先招待敗家教主到＂五子登科林＂內遊玩，接著再到＂奶粉尿布池＂中浸泡，最後再沒頂於頂級功力的＂學費帳單海＂之中。相信敗家教主一定可以洗心革面，悔不當初！
敗家教一袋弟子dennile，念爾年輕，並無大過，速速悔改！否則光只＂奶粉尿布池＂一招，便足以令爾永不超生！ 

後記：

CRK為何一定要裝上這個東西，來限制刀主人調整鎖片的彈力？我想原因還是在於他的陶瓷珠鎖定，陶瓷的特徵除了硬之外，就是摩擦係數低，因此用陶瓷珠來鎖定刀刃時，如果鎖片的彈力不夠，會有鎖定打滑的問題，也就是意外解鎖了！

而且還有一個問題，陶瓷珠的硬度比刀刃高，會在刀根的鎖定面逐漸磨出一個凹槽來，而且這個凹槽表面會很光滑，也就是摩擦係數會更低，因此刀子使用一陣子之後，更要擔心鎖定的意外解鎖。如果刀主人將鎖片的彈力降低，一開始時可能查覺不出來，但是在一段使用時間之後，就有可能發生意外解鎖的狀況。因此，CRK才會加裝這個鎖片限制盤，來禁止刀主人調鬆鎖定的彈力。

基於上述摩擦力的討論，Umnumzaan的鎖定力度必須比較大。但是對於折刀的鎖定，我一直排斥過強力道的鎖片設計，原因無他，就是容易造成鎖定的磨損。鎖定的力量越大，磨損就會越嚴重，鎖定的壽命就降低！

平時折刀子正常使用時，受力的方向還是在於止刀柱，鎖片很少直接受力（除非是射飛鏢、持刀格鬥）。所以對一個正常使用刀具的消費者而言，如何減少鎖定系統的磨耗，增加刀具的壽命，才是首要關注的事項。

再怎麼分析，從SEBENZA到Umnumzaan，看到的都只有『化簡為繁』的失敗而已。
