To illustrate the difficulty in the identification of leklai there are quite literally dozens of different leklai recorded in Thai literature, and here are a few examples :

Leklai go-thi-phi

 is dark green in colour, found only in deep caves or on cliffs. Has lots of manifestation power.
黑金鎳萊-罕有的流鐵之一，因為一大塊黃金鎳的原礦中，只能取出一點點黑金鎳就好比一大塊原礦只能取得一小塊潔淨的翠玉一樣，所以珍貴度很高

Leklai jau-pha

is black in colour,shinny, very beautiful, it hides among rocks, has high energy too.

黑鎳萊-一般最常見的流鐵，呈色黑，未經過加工，外型多元化黑鎳萊-一般最常見的流鐵，呈色黑，經過加工成為膠囊形狀，方便佩帶

Leklai yoi

藍光鎳萊-呈色特別的流鐵，因呈色泛藍金色的光澤，又被稱為藍金鎳萊除了以上圖片中的流鐵之外，泰國有人在研究的流鐵，起碼還有一二十種以上陸續不斷在增加中，像督造法刀聖器常用的譯音：鎳南霹或修行者（魯士）鎳萊或外形像枯木的譯音：鎳萊Yoi…等等，可以說種類非常非常之多，礙於版面因素未來有新圖片資料，再與館友分享；而每種流鐵的磁性，可能依礦區而皆有不同例如不同礦區所產的同樣是屬黑鎳萊，有些就具有強磁，甚至被當成磁石一樣，有些則是具有弱磁或無磁性、有些不帶磁性，不過當被磁石靠近時，會微被吸引，可見流鐵（鎳萊）並不能狹義區分它、或像坊間有人去自創流鐵（鎳萊）的等級！不管是哪一種流鐵（鎳萊），它的功能在泰國民間，普遍有同樣的說法那就是「流鐵（鎳萊）對財運生意很好、可避災擋險，讓壞事邪氣不會近身！」

Leklai chii-phra-kaaw

Ajaan Boon divided Leklai into 2 separate categories:-
1) The monk will gather Plai-dhum,Kamin  and  Kaaw or Mae-perng from forest and by using transcendental meditative power he is able to charge with materials with supernatural energy, making them denser with energy until turning into a rock and subsequently Leklai which is greenish in coloration.This Leklai will become so powerful that no one has the ability to destroy it,not even the monk who created it.1..僧侶將森林裡面收集到的Plai-dhum,kamin和kaaw或Mae-perng，使用超自然卓越的冥想能力，結合物質與超自然的能量，製作密集的活力，直到變成石頭，接著這個流鐵是綠色色澤。流鐵將變成非強強大，沒有任何物體有能力去破壞它。甚至沒有修道士能創造它。

2)The oldest Leklai [In Thai called "Koth Leklai"],  can
only be found deep in caves or high cliffs found in dense jungles. If the person is kind hearted and has gained sufficient merit, he can easily cut leklai from the cliff. The Leklai can change colour from black to dark green by prayers, it is easy to carry along and it will protect the owner at all time.However please note that Leklai should never be tested for its efficacy.
2..最古老的流鐵〈在泰國稱為〝Koth Leklai〞〉只能發現在很深的洞穴或是高的懸崖峭壁，發現在密集的叢林裡。如果此人有親切的心和獲得足夠的價值，他能輕易的將懸崖上的流鐵切開，這個流鐵能經由祈禱，從黑色變成暗綠色，它無時無刻都容易吸引和保護持有人。然而請注意，這個流鐵不會被測試它的功效。
金屬的" 國王"因為它(這)含有(容納)強壯(強烈)保護的可以(可能)對誰總是處於殺的危險狀態的警察或者士兵理想。
